^^ I dont believe ARE has a reinforced option.. I would definitly look into his claims.
Mt Tepui weighs in at 130 lbs. When it's opened up, the ladder supports half the weight, so now there's only 65 lbs that the cap is supporting. Now with me and the dog in it (250 lbs combined) the cap is now only supporting 190 lbs. Add a few pounds of sleeping ear and I wouldn't be scared of having a RTT up on a cap.
I've read that leer and other truck toppers shouldnt have to much weight loaded on top of them such as a roof top tent. Soo I dont undertsand how an outfitter would carry a tent up on top..I'd love my tent on my cap but am so hesitant..
I'm running a SnugPro Commerical Grade fiberglass canopy. It is rated for 500lbs. It is plenty strong for the tent, rack, awnings, etc. But... The truck bedsides are not strong enough. I started having issues with them spreading. It was resolved by adding a spanner bar to pull the bedsides together. I'd recommend limiting how much weight you put on the bedsides. Getting some good vertical support to your bed/frame is a wise idea.
