i was looking at leg levelers and the weight and cost of each and wasn't sure which one i needed to put on the bottom of my cab. if i have 4 levelers and each can hold 200 lbs each, can 4 levelers support 800 lbs? i was looking at happs levelers that are under PC Arcade-Accessories (by the way, how do you put a link here to happs products? do you just put a link to the price page?). i'll be building the cab from LuSiD's plans.
