Question:

Our 2021 Ram 3500 Promaster Coachman Nova Li3 Camper Van now pulls a NOBO 10’ Toy Hauler to Cary all our gear lots a GearHad Van Lifted 3”, F and R, off road tires. When partial loaded ok, when fully loaded and balanced, we got issues. Originally looked at SuperSprings helpers but now the RAS77VR SPECS OUT BETTER. Van has Sumo yellow R, spindle lift R, Strut lift spacer top F. Does having 3” Lift affect either of the led spring helpers. After reading bout both RAS appears to solve all issues when all toys loaded. Cat Scales weighed first trip with THauler 2 times same nitedon’t fully understand and read bout all ya tips and more med load out first weigh. Second weigh Steer Axl-4080. Lb 00 lb Drive axl -5420 lb. 9480 lb Trailer axl -3580lb 3580 Gross weight - 1380. Lb 1360 lb How bout your recommendation - I’m gonna load heavy every chance I get!

As long as you did not change the leaf springs then you are going to be able to use the RoadActive Suspension # RAS77VR on your 2021 Ram ProMaster 3500. I do wonder if you have considered using a Weight Distribution Hitch # FA92-00-0600 to connect the trailer. This will help to redistribute some of the trailers tongue weight back onto the front of your ProMaster.
