Wow! That's like asking what color of paint should I paint my bedroom. The sky is the limit.
Posters on these forums seem to say, select the camper first, then get the truck to match. For the longest time I disagreed with that statement. It's only taken me 60 years to finally figure it out ... (they ARE right). Find the trailer that interests you, then begin looking for the truck that will provide a comfortable tow. Otherwise, the only trailer you may find you are able to tow will be a pop-up. By the way, a 3/4 ton WILL handle about 90% of the campers out there. But you also have to figure out gear ratios and hitch weights too.
