I've reached a point where I'm tired of camping on the ground...... it's camper time! I'm looking for something that I can bolt-on my '89 Blazer (in place of my hardtop)... and it looks like my best options are either the late 70's Chalet/Casa Grande campers OR the "no-longer-produced" Pop-up campers (which were made by Four Wheel Campers, Hallmark, and a few other company's) Questions: 1. Any recommendations or tips? 2. Which of the above campers offer the best strength? 3. Which are less weight? 4. Anyone know of any for sale? Thanks for any advice!
