When buying a 5er payload is the number you have to worry about the most, but you need to check all the numbers. I keep seeing people saying if it was up to the weight police everyone would be towing popups with DRW 1 ton but on the other hand if up to the 1/2 people they could 20,000 lbs 5er with their 1/2 ton just add air bags.
This is not rocket science and its just simple 5th grade math. It just comes down to a numbers game and if you believe that staying within the manufacture GVWR specs and keeping you and your family safe or not.
The numbers below came from Tow Planner -
Towing Calculator based on Truck's Payload/CCC - Towing Planner
Most trucks run out of payload long before they run out towing capacity. Tow Capacity Ratings reflects TT weights which have lower payload requirements. The numbers below are from tow planner with only a 175 pound driver and 250 pound hitch and nothing else in the truck (total of 425lbs). If you added a passengers, wood, cooler and etc you must also subtract those weights. Remember not to use the dry weight but ready to camp weight when figuring the weight of you 5er.
