I just bought a 1992 21 ft. Prowler for $1000. I figured I couldn't go wrong. I'm a former pop-up guy. I assume that it has brakes. My 1999 Suburban has a tow package and has pulled my former heavy pop-up easily. Do I need a special braking box added to my Suburban? That's what the local trailer guy says. Also, what's the best stuff for fixing a leak around the air conditioner? In addition, is there a site that has all the specs for older trailers like this? Thanks.
