First, welcome!
OK, your 6500lb dry weight camper will be at least 7500lbs loaded. that is border line 1/2 ton. I would look at a 2500 also. lots out there in your price range. diesel is not necessary but nice to have, a bigger gas V-8 or V-10 is necessary. just look for a well cared for truck. you don`t want a piece of junk. yes most any truck will have a class 4 hitch which is a 2" opening. you will also want to use a Weight Distributing hitch with any truck you get.
Tow rating is just that, how much the truck can tow.
GVWR, the most the truck can weigh with all people, cargo and trailer tongue weight with hitch attached.
GAWR, the most each axle can weigh, this number usually adds up to more than the GVWR. these are the numbers you don`t want to exceed!
CCC, the weight a vehicle can carry. this will be the difference between curb weight (weight the truck or trailer weighs when sitting in your driveway) and the GVWR. for instance, my trailer has a 7100lb dry weight and an 11,200lb GVWR for a CCC of 4100lbs.
You will learn a lot here, both good and bad LOL! so keep on reading and you will slowly learn some great things.
