If the OP said “Yep, planning on this truck pulling that camper for years and years, full time or frequently and cross country a bunch.” , an upgrade to a 3/4 ton would at least be somewhat warranted or desireable.
But presuming he’s the typical weekend warrior, he has a great truck for the combination of occasional towing and daily driver duties. As long as the E torque holds together (nothing to do with towing, but I wouldn’t own one due to the added complexity and potential/real failure modes) the engine and trans are right up there with any 3/4 ton gasser save for the Ford 7.3.
