My husband is about 225 and he has the Safari and loves it. I think it will hold your weight, but only you can check it to know for sure. The material is very heavy duty. My husband slept in the Safari and the TTG Switchback this past weekend, and he preferred the Safari for its size and comfort. He said he likes the big size of the Safari and it is much more comfortable. After sleeping in the SB until about 0230 hrs. he couldn't get comfortable and then went and slept in the truck, because I took down the Safari.
However, it is HYOH, and this is just my $.02.
