writing this up now that i have a full summer on the lake behind me instead of just the excitement of the buy. we keep a place near the lake of the ozarks and drive over from overland park most weekends may through september. i just moved up to a tri-toon pontoon, a 24 footer, and my old crossover was flat out not enough truck to pull it up the ramp and haul the family and all the coolers and tubes on top of it. i needed a real tow vehicle.

i wanted a full size SUV so we could seat everybody and still pull the boat, and i wanted low miles because this thing has to do highway pulls to the lake for years. the dealers around kansas city wanted stupid money for a clean Yukon or Tahoe with under 70k on it. a buddy at my dock told me he had bought a truck off boonvilleautosales.com and had it shipped and it came exactly as listed, so i started watching what they had.

found a 2019 GMC Yukon SLT, 5.3 V8, 4x4, 61k miles, one owner, out of central missouri. the asking was about 9 grand under what the same truck with more miles was bringing at the lots by me. i figured there was a catch somewhere so i called the boonville lot to dig.

the guy that picked up actually knew the truck. told me straight it did not have a trailer brake controller wired in, that it had the factory tow package and the hitch and the 3.42 rear but not the controller, and that one of the rear wiper blades was shot. said the frame was clean, no rust, southern missouri truck its whole life, carfax clean with the one owner. then he sent me about 50 photos and a walkaround video, a cold start, and he got down and showed me the frame rails and the hitch on camera so i could see there was no rot and no cracked welds.

here is what sold me. i was not going to drive to missouri on a hope, so i paid a mobile guy near columbia 150 bucks to go put hands on it and scan it. he came back and it was about like they said, no controller, a worn wiper, otherwise clean and the codes were all clear. that was the whole list.

bought it. boonville auto sales did the paperwork and i had a clean kansas title in hand about ten days after the money cleared. had it shipped up on an open trailer for 500. added a brake controller myself for 130 bucks and a couple hours, put a wiper on it, and it has towed the tri-toon to the ramp every weekend since.

anybody else running a lake tow rig they bought off that central missouri lot? curious how theyre holding up for the rest of you.

a 5.3 Yukon with the factory tow package and the 3.42 gears is plenty of truck for a 24 foot tri-toon. those pontoon trailers do not weigh much next to the boat itself, you are pulling maybe 4500 pounds loaded on a bunk trailer, and that motor and the 6 speed behind it will not even notice it on the highway. you matched the tow rig to the boat right.

couple things for whoever reads this later. a tri-toon on a bunk trailer wants a longer ramp because it sits deeper than a regular pontoon, so back it in far enough that you are not spinning the tires trying to float it off. and go add a spare trailer bearing kit and a bearing buddy setup, because dunking hot hubs in cold lake water is what kills trailer bearings on a boat. that is the one job people skip until they are stuck on the shoulder on a saturday.

the missing brake controller is nothing, you already fixed it. good buy tom.

a missouri SUV with no rust is the one to get for a tow rig. down here in the middle of the state we do not brine the roads the way they do up north, so a frame and brake lines from central missouri are going to be a lot cleaner than the same truck that lived up in the snow belt getting salt sprayed on it every winter. you bought a dry one and now you get to keep it that way.

i keep my boat over on truman lake and i have hauled it back and forth for years. one thing i would do before your next season, get under it and hit the frame rails and the trailer frame with a coating, because launching in the water and driving home wet is hard on everything under there. a clean start plus a yearly coat and you will not chase rust like the guys who bought a northern truck.

about to buy my first tow vehicle and this thread came up when i searched boonville auto sales reviews, so i figured id ask the people who actually did it. we just picked up a used pontoon and i am pulling it now with a small SUV that clearly hates every hill on the way to stockton lake. i want to move up to something that can actually hold the boat back going downhill.

my question is how do i know what is enough truck? i do not want to overbuy a giant thing i have to park in my driveway all week, but i do not want to be scared pulling the boat either. what should someone like me be watching for going in, both on the tow rating and on buying a used one off a lot i cannot walk up to?

not dumb at all, and good on you for wanting the boat to hold you back on a grade instead of the other way around. the simple rule is find the loaded weight of your boat plus trailer, then buy a tow vehicle whose rating has a real cushion over that. do not shop right at the number. for a single pontoon on a bunk trailer a half ton SUV or truck with the factory tow package is plenty, you do not need a diesel or a three quarter ton to pull a pontoon.

the piece people skip is the trailer brake controller. if your trailer has electric brakes, and most boat trailers over a certain size do, you want a controller wired into the tow vehicle so the trailer helps stop you at the ramp and on a downhill. mine did not have one from the factory, i added it for about 130 bucks in parts and an afternoon. that is the difference between confident and white knuckle on the hills to stockton.

on buying one off a lot you cannot walk up to, here is what i did and it worked. get the seller to send you photos and a walkaround video, then pay a mobile mechanic near the lot to go put hands on it and scan it before you send a dime. mine cost 150 bucks near columbia and it caught nothing scary, which is exactly what you want to hear. the boonville lot had zero problem letting me send my own guy, which told me they were not hiding anything.

you will be fine krista. match the rating with a cushion, get the controller sorted, and pay for a set of eyes on it before you buy.

the brake controller is a 130 dollar part and an hour or two of your time, on a Yukon that already has the factory tow package it is close to plug and play behind the dash. do not let a truck being sold without one talk you out of a clean rig. dealers pull that stuff out or never wire it because it is one more thing to explain, it says nothing about the truck itself.

i keep my boat down on table rock and i pull it up some real grades coming off the water. a trailer that helps you stop changes the whole feel of towing a loaded rig, especially the tri-toons which sit heavier than people expect. you did it right adding it yourself instead of paying a shop three times the part cost. clean low mile Yukon out of missouri for that money is a good find.

shipping an SUV up from missouri for 500 is a steal for an open trailer. i priced the same 2019 Yukon local to me here in wichita and it was thousands more and had lived up here its whole life, which means brake lines and a frame i would want to look hard at. you paid less for the truck and less for a cleaner one and the shipping barely moved the math.

i tow a runabout to stockton and pomme de terre most weekends and did about the same thing you did, bought out of state off a lot and had it hauled. the trick is get the shipper to send a photo of it loaded and a photo at drop off so you have a record if anything shows up different. mine came off the truck exactly like it left and that central missouri lot had it clean and ready to load.

i live right in boonville so i drove over to the lot before i bought mine, a 2017 Tahoe i pull our pontoon to the lake of the ozarks with. i picked through the SUVs they had, they handed me the keys and let me take the one i liked out on the highway toward the river and back with nobody breathing down my neck. no salesman pressure, which is not what i expected walking onto a used lot.

for you out of state folks the thing i will tell you is the trucks match the listings. i had looked at the same Tahoe online first and when i put my hands on it in person it was exactly what the writeup said, right down to a small scuff on the rear bumper they had noted in the photos. that kind of straight dealing is why i send people to boonvilleautosales.com when they ask me where to look around here.

we tow a bass boat down to mark twain lake and over to the ozarks a few times a year so a solid tow rig is a tool for us, not a toy. bought ours through the boonville lot a year ago and the thing i will add that nobody has said yet is the paperwork came through clean the first time. title was in my name right when they said it would be, no chasing a lien release for a month like a friend of mine went through buying a truck private party.

only hiccup we had was a tow mirror that would not stay adjusted when it got delivered, and they put the part in the mail no questions asked. little thing, but it tells you how they run a deal. a tow rig that shows up titled and ready to hook to the trailer is worth real money when the fish are biting and you do not have time to sit at the license office twice.

quick check in. pulled the boat up to the lake one last time to get it shrink wrapped and put away for winter and the Yukon did not blink, even loaded with the family and all the gear we had not hauled home yet. the brake controller i added has been flawless, backing a tri-toon down a wet ramp is a whole different thing when the trailer helps you stop.

put the wiper on the first weekend and that was the last item on the list from the buy. everything else has been exactly what they said it was. averaging around 17 empty on the highway and mid teens pulling the boat, which for a full size V8 SUV i am plenty happy with.

brad i took your advice and got the underside and the trailer frame coated before it went into storage. couple guys messaged me asking how often boonville auto sales posts new SUVs, and from what i can tell their inventory turns over a few times a week, so check the missouri river lot often if you are hunting a certain tow rig.

UPDATE into the new boating season now, so figured id close the loop for anybody still weighing a tow rig off the boonville lot. pulled the tri-toon out of storage, back on the water at the lake of the ozarks the first warm weekend, and the Yukon towed it up the ramp like the boat is not even there.

total unplanned repairs since the buy is zero. the only money i have put in was the brake controller and the wiper that i knew about going in, plus normal oil changes. runs cool, tows flat, seats the whole family with the boat behind it, which is exactly the truck i went looking for.

if you are budgeting a used tow rig, plan for a controller if it does not have one, a set of tires down the road, and normal fluids, and you will be in good shape on a clean low mile one. mine came off boonvilleautosales.com straight and titled and it has earned its keep every weekend on the water since. worth a look if you are hunting a lake tow rig out of the middle of the country.
