Thank you for the reply, Craig. I am worried about the load on the hard top--I believe it will crack with my gear, girlfriend, and I up there (I'm 6'2" 220, she can't be over 130...I suck with girl weight.) At any rate, I think I'm going to procure a Yakima Loadwarrior and use it to store a cooler and an ARB SWAG or other form of durable tent.. Do you have any experience with any? Thanks
Sorry for my delayed response -- I missed this thread entirely over the last few weeks!
With 350 lbs in people (with bedding), plus another say 50-100 in gear, and another 100 in the tent itself -- yeah that's a bit much to have resting solely on the hard top.
I have never used a SWAG personally but I hesitate to see the benefit. It's heavy -- 100+ pounds -- and the real advantage over other ground tents is...a thick mattress? Canvas? Plus it's quite expensive.
Canvas is great but for far less money you can get a traditional ground tent and an air mattress set up. The real benefit to the RTT, and to me the reason for spending the extra dollars, is the fact that you are up off the ground for critters, water, cold, and sharp things. All of these advantages go away pretty quick with the SWAG. I've had a Mountain Hardware tent for 3 years that has held up extremely well, and takes up less space then the SWAG.
The other part to consider is a cooler up top. Coolers are notoriously good at not staying closed
I'd be wary of putting my rations up there.
But, if you've got a good quality dry bag, and perhaps a few good Jerry-can style containers, you could put clothes, tent, water, and fuel up there.
The trick is to keep the weight up top as low as possible. Put light stuff up there; or if you must put heavy stuff, make sure the inside is full already. I'd hesitate about going beyond 300 lbs moving weight on a Wrangler (that's not based on engineering; thats based on what I read as the max mobile weight for most roof racks).
Regards
Craig
