Can I tow with my Ram

Technically yes, but your truck has a payload of 1540. You have a crew cab. That sometimes implies more than just one person in the vehicle. The camper is a bunkhouse.. so.. now we start to weigh the family, the hitch, the toys, and the overall weight on the hitch.

Empty, the hitch weight is 775. I think the payload would be over and you quickly get into the uncomfortable feeling. Better off with a bigger truck I think.

Sure but you will need to educate yourself on all aspects of towing to do it right
