Towing an Eagle HT 27.5 with a F250 SD

Need to pick some brains here. We just bought a 2017 Jayco Eagle HT 27.5RLTS in Indiana. We are from TN.

Here are the specs on the 5er:

Unloaded Vehicle Weight = 7865
GVWR = 9950
Dry Hitch Weight = 1490

We're towing with a 2008 F250 Super Duty 5.4 Gas Engine. Unloaded, the 5er is squatting the truck somewhat. (We know about the option of adding the air bags.) It towed fairly well, but coming over the mountain from Kentucky, into Tennessee, the engine was struggling and 50 mph was the best we could do at 3500 rpm's.

Do any of you have a similar rig, and if so, what do you tow with? DH is wondering if there is anything we can do, short of trading for a diesel. We were told over and over that our truck would pull this, so we weren't planning on buying another vehicle. Thoughts or suggestions?

Your truck will pull it, just not very satisfactorily. You don't say what rear end you have in the truck, but if it's a 3.42 or so, you will have a tough time pulling up hills and mountain passes. Our 26.5 RLS "squats" my GMC 3/4 ton 2500HD about one inch, measured the first time we hooked up. Depending on the squat, you might want to install some air bags or additional springs. However, I would wait to do that in order to find out if your truck really will pull satisfactorily. I did have a Ram 2500 diesel with a 3.42 rear end and I looked at changing out for a 3.73 or something around that ratio. Figured it probably wouldn't fix my concerns about the truck so traded it for the GMC and haven't looked back.

Easy answer would be to buy yourself a 3/4 or one ton diesel and you won't have any problems, but that might be an expensive fix.

I am towing with a 2010 F150 with 5.4 and similar weight to you with 28BHBE tow trailer (but less tongue weight) My warranty recently expired so I added a Livewire TS tuner from 5star tuning with Custom tunes. Website claims an increase of 40 ft/lbs of torque which, while not earth shattering, is a 10% increase. While it requires premium fuel, it is worth it while towing. It also changed the shift patterns and locked out 6th gear and holds gears a little longer with the Tow Haul mode engaged.

I definitely noticed an improvement in acceleration while climbing hills and mountains with the trailer hitched up on a recent trip to Lake George, New York. There are a couple of steep climbing stretches where I had to slow down behind semis to allow traffic to pass and was able to accelerate past the semis while still climbing. Did the same stretch the year before and accelerating past definitely took longer. My truck seems to not have to work as hard to maintain the speed limit. I also like being able to keep an eye on temperatures while towing.

I don't have any experience with a similar combo but I do know that the 5.4 likes to rev and you won't hurt it revving it up. Other than the noise it is fine.

Once I got used to revving up our 6.2l engine it performed much better than it was when I was trying not to let it scream.

Your rig is capable and unless you want to go for a diesel you will have to just be patient climbing some of the steeper hills and mountains.

Cheers

Sorry, I forgot to include the gear ratio. It's 3.73. You all are making me feel much better as I did NOT want to put more money into another truck. DH bought this truck in 2013 when he retired. It had low miles on it and we hardly use it, so the thought of trading made me ill. LOL

We were concerned about the "screaming" as Subaru297 called it. We were concerned about blowing up the engine, so I'm glad I asked my question. Thank you all for your help!

Believe it or not, you're close to your weight limit with that engine. You have a 3.73 rear.


9900 lbs. tops TT (depending on your cab style and 4X2 or 4X4)
10,000 lbs. FW

7900 lbs dry trailer + you + DH + kids (if any) + ANYTHING you put in the truck + ANYTHING you put in the trailer.


10,000 lbs. is closer than you think. 2100 lbs. goes fast.

Your 5.4 is a bit of a turd, for lack of a better description. Not saying that to excite Ford owners, but I had that exact same truck as my company work truck, back in '08. Just not enough engine there for what the truck is capable of, and nothing much you can do about it. I used to pull a large goose neck trailer from job site to job site, some of which were up in the mountains. You just have to get used to being a rolling road block in the right lane, or trade up to a diesel.
