The problem is not usually the “tow capacity” it’s usually the payload. As the truck gets more options, the payload goes down so usually a more base model truck can haul more than a loaded one. You need to look at the trailer LOADED weight and multiply that by .15, that’s a realistic tongue load. As an example, just picking numbers out of the air, let’s say the truck you are looking at has a payload of 1400lbs, and you have a 6000lb GVWR trailer. The tongue is ~900lbs. Add a weight distribution hitch and you are at 1000lbs. You then have 400lbs for people, dogs and cargo in the truck, which isn’t much BTW. I highly recommend trying to zero in on what camper you want to buy and then make sure the tow vehicle can meet that requirement plus a safety factor. You don’t want to spend $50k on a truck that can then not tow the camper you want. Also, ignore dry-weight, your camper will never be empty. That’s marketing nonsense just like the vehicle manufacturers “tow capacity”. Ultimately neither the vehicle manufacturer, trailer manufacturer or either of their dealers are responsible for you matching the wrong truck to the trailer. If you have an accident and have exceeded the tow vehicles capacities you are technically breaking the law and your insurance may deny the claim, and hope nobody was hurt because then the lawyers get involved. Ultimately it’s not about power, it’s about stability.
