- 5.7 Hemi Crew Cab,
Today I picked up my Grand Design Imagine 2600rb. I’m a first time RV’r. I was incredibly disappointed as to how the 75 mile ride home went. It was all expressway and mostly flat (It is Illinois) and my truck rarely made it out of 5th gear! My truck is a 2020 Longhorn with a towing capacity of 8120 lbs with a max payload of 1770lbs. 5.7 Hemi with e torque and 3:21 gears. 8HP75 transmission. The trailer weighs 5800lbs dry and since it was new there was nothing loaded in the trailer yet. I used a weight distributing hitch, Equal-I-Zer brand.
At 62mph (with everyone passing me) in a 70mph limit, the truck was revving at 2700rpm’s in 5th gear. I did use tow haul to enter the expressway but turned it off once speed increased. There were a few times on a slight downgrade that the transmission shifted into 6th gear and one time coasting it briefly went into 7th gear but it was brief. The Electronic Range Select (ERS) was not engaged. Upshifting and downshifting were fine.
I have never had any problems mechanically with this truck and up until today (with exception of some Rambox latch problems) I have loved this Longhorn. The 5.7 has always been a good runner for me.
So, please, I’m looking for suggestions from experienced RV’rs as to what is going on here? Is the 3:21 gear the culprit? Did Ram overstate the towing capacity? Just because the truck’s frame and axles can physically carry the weight, maybe the transmission isn’t equipped for towing. I’m leery to add the usual weight of daily necessities for a trailer trip let alone hitting any hilly areas. After at $70K for a truck and another $40K for the trailer it quite disappointing. I’m desperately seeking experienced analyses.
Thanks in advance,
Hank
