Looking to tow 8000 lb trailer with a Hemi

345hp should do a lot better than 35 up a 6% grade with only 5000lbs behind it.

I agree; with my 2003 hemi 5.7L with a 5-speed auto, I often did 6-8% grades at 50 mph towing an 8,000-lbs 5th wheel.

Just as a note, the new ones like my 2014 have 395-hp and 410-lbs of torque with an 8-speed.

I towed a 5,000lb TT with a 2004 Durango Hemi 5.7L. Towed with ease but I would not want to tow much more. Up steep mountain grades, 6% or higher it was down to 35mph and rather high RPM's. Would be uncomfortable to tow higher loads up the grades.

Essential for our Hemi was the factory auxiliary engine and tranny cooler. On a hot summer day the engine temp would climb way up and then the aux fan would kick in and the temps would quickly drop back to normal. Would certainly over heat without it.

Towed my 7k trailer up the Mogollon rim 6% for 10 miles pinned WOT for 13 minutes at 45 mph top speed in my heavily modded 99 Tahoe. It did it but hated the 7500 ft elevation.

F350 7.3 had the advantage of turbo in the high elevation, 65+ mph no problem.

If towing less than 3000 ft it's all good, 5000 or higher and turbo is your friend.

I tow in the high 8,000-lbs with mine and I'm very happy with it. It's actually my 2nd 5.7L hemi truck.

My current one has 3:92 gears and the 8-speed. I use Tow Haul and essentially live in cruise control. I will manually shift down to 6th or 5th in heavy mountain terrain as required.

My last trip from South Carolina to Montreal I averaged 11.2 mpg towing the trailer. On interstates without the trailer I get in the low 20's mpg (typically 23 mpg)

I have a 2012 Ram 2500 Crew Cab, 4x4, 5.7 Hemi. 6 spd auto and 4:10 rear. It handles my Jayco Eagle very well at about 8500#

Why all the talk about weight? OP says it is a 3/4 ton, which will easily handle the #8000.

So will that 5.7 HEMI.

Truck is a 2014

I used to tow a trailer of similar weight with my 2014 Ram 2500, but I have the 6.4. Truck handled it easily.

What year is your truck? Check the payload ratings, you should be fine with a 3/4 ton truck. But if you want peace of mind, subtract hitch weight and any people/gear you will be hauling. You should have a good bit leftover. Also 8000 lbs should be within your tow ratings.

Should be fine, just let her sing up the hills.
