I’ve got an 04’ Hemi Ram Quad Cab 4x4 with around 130,000 miles on it. Mechanically it’s in great shape…no issues at all. I’ve recently picked up a 19ft camper trailer that weights around 4,000lbs….and the family and I are planning on doing lots of road trips, most around 12-16+ hours. Are there any items that I should upgrade on the truck before I do all of this towing? It’s got good brakes (aftermarket rotors & pads), and it’s got the factory towing package on it (not sure what that really gains me). Anything else I should look at upgrading?
