My default plan is to order a 2500 gas 4x4 Big Horn CC short box for towing travel trailers or small 5W's. It just become possible to do 2022 builds on ramtrucks.com, and I played around with 3500 builds as well as 2500. I was surprised to find just a small price increase going from 2500 to 3500 with similar configurations. For the 3500 I didn't find an option for limited slip diff, so I assume it is standard for 3500. I know that the suspension in the 3500 would be less comfortable in the 3500 when driving unloaded, but maybe the ability to tow bigger 5W's would be worth it? THe 3500 must be heavier and get poorer gas mileage, but by how much?
