I have a tepui kukenam camo bolted to my two factory crossbars that are rated at 80lbs each. I also added two more crossbars that I got from the scrapyard just to be safe on weight distribution. The tent weighs 130lbs and my girlfriend and I combined are 320. We just spent a month sleeping in it and driving 10,000kms with no problems whatsoever. I was unsure at first but it worked out great and kept the tent nice and low to the roof.
I gotta recommend getting a tepui as well. The materials and quality is top notch. Well worth the price IMO. lots of headroom, comfy mattress, all bedding blankets, sleeping bag and pillow fold up in it, and it performed very well in the 3 day downpour we had in the Yukon.
Hope this all helps. I'll try and post a pic tomorrow for everyone to have a look, cheers
