Has anyone placed a 750lb fat sac on top of the stock 400lb sacs in the rear compartments of a 08 Supra 22. I want to inflate the 400lb stock sac in the rear and then inflate a 750lb fat sac right on top. Would the 750lbs fat sac bust the 400lb sac or push water back into the stock ballast system.
I did just this on my 07 Moomba XLV just this past September to get a good surf wake going and had no problems. I may make something this winter though to support the weight of the 750 sac on top, kinda maybe box the lower sac in.
