Crashmaster,

You just gave me some great ideas for my 4X8 closed trailer.

The trailer

I am going to try configure a PVC wheeled rack system in hopes that I can get at least four planes along with the wings as well. I want it to be completely removable so that I can still access the rear of the trailer. This will take the place of the current wall rack system I am using.

As far as the PVC welding goes there is no need to weld them just use a 3/32 drill bit drill a hole or two, one on each side if want then use a black flat head 1/2" roofing screw to secure both the pipe and fittings together, That way you have no worries of them coming apart and you can always adjust them as desired. If you notice in the trailer I use the screws to secure the pipe to the wood with.
