A slide in generally sucks all around. IMO get a small bumper pull in the 20-24ft. range and have more room without too much more weight. Also, electric trailer brakes will make your life safer, and keep some brown stains from forming on your seat. I had to tow one of our work trailers the other day, and while I was using a 05 K3500, it sucked without trailer brakes. The same trailer after I stopped and re-wired the plug let the truck stop as if nothing was behind it. I towed the same trailer behind my 88, and while it got it moving fine, it was downright scary with no trailer brakes. This is with the 3/4ton rear brakes, and all pads and rotors in spec. And that was only about 3K lbs, I can't imagine a 5-6K lbs. camper. A trailer brake controller is a great investment if you tow more than once a year IMO.
