Size depends on if it's just you or if you have family. We started out with an 18' to hunt out of then my wife decided to go so now there's 4 of us. It was like a sardine can we graduated to 24' all the while kids getting bigger. We now have a 34' KZ SPREE bumper pull with bunks and super slide. If you have family bunks are great not the kind they stick in a corner but a separate room. Slide out is a must plus all the appliances. AS much storage as you can get then some. As far as weight there's a lot of lightweight campers including fifth wheels that are 1/2 ton towable. If camping in the winter always carry a extra bottle of propane or know where to get it,the gas furnace sucks it up. But I would start with 24'-27' either way. A good weight distribution hitch plus sway bar is a must. Make sure you shop around and don't get a camper where the bunkroom has a slide that slides directly out the rear, they tend to leak.
