I have an Apache pop-up camper. Does anyone know how much weight I can put on the roof and still be able to raise the roof without unloading it. I want to put two kayaks on the roof which will probably weigh about 150 lbs including the weight of the rack.
Newenglander,
I have a 1999 Apache popup slide-in that I bought in 2005. I removed the roof air (didn't want or need it) and instead carry a Pelican canoe on a Yakama rack on top. Weight is probably around 100 lbs total. It cranks up ok; need to use a bit of muscle, but not overly tough (my wife can raise it ok). I've driven it on lots of rough desert roads/trails and it does just fine.
I suggest putting a tarp over the top to protect it, set the kayaks up there and see if it works okay before installing the rack. Hope that helps.
