For those with 25-30 footers towing with half tons… I have a 6.2 1500 that pulls my 27’ Fountain. It does pretty good from a suspension perspective, but when I get into areas with rolling hills, the motor is working!
I’ve looked into diesels, but I just don’t want any to pay the premium. I like my half ton and if it had a little more juice, it would tow just fine.
Seems heat is the issue with most gas/turbo tow setups. Has anyone done a low comp setup with a small turbo for a tow application?

How much gear does your truck have? 3.42? That boat and trailer probably weighs around 6500 lbs. The 6.2 is better than the smaller 5.3 and I believe if you get the max tow package it comes with a 3.73 rear, but perhaps you already have that. If you do, you could swap in aftermarket 3.90 or 4.10 ratio gears if you tow a lot in hilly terrain. Those ratios would of course reduce your non towing fuel mileage some.

I’d rather put 6-10k into an upgrade on my existing truck and accomplish what I’m after. Just curious if anyone has done something similar.
If I had a bigger boat, without hesitation, I’d go bigger and diesel.

I towed my Tiger for years with an 01 8.1/Allison dually, while towing up to lake Champlain we compared fill ups, i had to stop more but in the end the cost of diesel made my tow less expensive. also how good is the trailer, I made the switch to 14 ply tires and it was night and day, i also used equal in the tires for balance. I would think there is a tune available as well for your current setup to optimize it.

I have a 2016 YukonXL Denali w/6.2 8speed and pull close to 7000 including trailer, 270 Checkmate.We tow a few times a year to Central Pennsylvania with one hill 1000 ft up and down. That said I thought of going diesel but will pass as vehicle does well. Home elevation is about 1000ft and peaks to 2500ft and lake is back to 1000ft.

I towed all the Cigarette's I had with 8.1/Allison trucks and I still have one that I tow the Concept with. Never skipped a beat. Gas trucks are fine, Diesels are great, but you do pay a premium and if you don't tow all the time, sometimes the numbers don't justify the purchase. Good luck, for what you are currently pulling, I would not worry much. Could always step up to a 2500, but again its going to cost ya.

I think a 6.2L 1500 is more than enough truck for towing a 27' Fountain. I towed similar sized/weight boats for years with 1/2 ton vehicles from 5.3L 1500's to 6.0L Denali XL's (Suburban). I'd throw a tow tune at it if you can still get your hands on a tuner (thanks EPA). Made a big difference on a 5.4L F150 I had a few years back. My engines also didn't like the hills when I towed to LOTO but no longer than they were screaming over 4K to climb the hills I just lived with it. I did have a 2500 DMax ('04.5 LLY) for a couple years and of course the difference was night and day with towing but this was back when diesel was $1.99 - $2.39/gal and the truck new stickered for $44K and I think I paid about $33K for it as it was still sitting on the lot in September as the '05's were rolling out. I always thought I was dumb for getting rid of the truck but if I still had it the rockers, fender well lips, cab corners, and brake lines would all be rotted away by now.
