Tie-down systems performance/safety vs cost

I have had both torklift and happijac mounting systems, they both do the job for me with a heavy camper. I agree that I did like not having the fuel door blocked with torklifts but that was easily fixed with fastguns. Now I have not rolled over my truck so I can't say how well either will do in that situation, but if I am at that point I figure I am SOL anyway. I do quite a bit of 4x4 in the sand and both systems have done a good job keeping the camper secured to the truck.

Btw, a member that upgraded trucks gave me his happijac system, I just had to pay shipping so keep an eye out for deals on EITHER system, best deal wins :)
