Good idea arbo06, In fact I use my wheels to help support the hulls on my Mystere 6.0. I have rollers in the back. The rollers in the front were replaced with store bought cradles. After the the boat is tied down I take the wheels up front and slide them on the tounge of the trailer until the cradles of the wheels sung up against the hulls.I tie them off there.This gives added support about 3-4 FT. forward of the main beam. Other boats,trailer combos may need some mods. One thing to look out for with this is to make sure there is enough clearance between the road and the wheels! You might have to go to a taller trailer tire and go up on the hitch ball hight to achieve it. One other thing remember the wheels use a hollow alum. tube. I don't think you want to use that to support the boat in place of the cross beams.
