2018 Ram 2500
Trying to figure out the towing capacity for 2018 Ram 2500 6.4 hemi with 3.73 axle short bed crew cab. We are looking into buying a 14000 lb fifth wheel. Has anyone pull this heavy of a fifth wheel w...
rmdbauer,
After all the giberoush below. GO find yourself a 5W with dual 5K axles, empty weight if you can in the 7-8000 lbs range. Also make sure it has the smooth fiberglass walls, no front bedroom slide. You can load this to around 11-12000 lbs, 2500 or so on the hitch, the rest on the axles. you will then be below all your manufacture performance ratings. You are beyond warranty time, so you are the warranty check book be yours to pay it under or over your ratings.
The fiberglass walled versions will be 400-800 lbs heavier than a corrugated aluminum wall version, but due to better aerodynamics, easier to pull overall, get you better mpgs etc.
NO you will not be the fastest rig on the road! You will have to spend $80-100K on a TV with one of them thar 400/1000 diesel crew cab pickumups to get what one person says you need to pull a 12K trailer.
I had the ability with my 2000 2500 reg cab C2500, other than the motor that came with it. If I would have had a 454, 4.56 gears GCW is 20000 lbs, vs 13500 with the 350 and 4.10 gears. This 2500 had all of 400 lbs less payload than my 05 DW Crew cab dmax diesel per the payload on the door label! BIG trucks vs smaller trucks do not mean better in all ways!
Enjoy RV'ing!

Says most people that are trying to justify their underpowered __________ vehicle. $80-100k? Lol. Sure you “can” spend that much but for new trucks, there’s some diesel 2024 Ram 3500s left in the mid $50s and new 2025s for $60-65k with the new 8 speed. Big screen, heated seats etc. Just not the $20k trim and interior upgrades.
Apples to apples comparing to the OPs 7 year old truck, you’re talking $40k for a very nice diesel with lower miles.
But that same sort of embellishment may also be the reason why you’re suggesting that a 25 year old GMT 400 with a big block could even think about towing a 14k 5ver even remotely well. (20k gcvw per your post). Even at low altitude here in WA it would be doing 25mph up any grade on I 90.
