Picking this up on Saturday, already ordered ski guides and one set of short and one set of tall Caliber flexible corner guides. Planning on cutting up and using 5 X 8 X 1/4" thick utility mats for the runners after applying sealer to the floor and ramp. No snow means I got a great deal. Any input on configuring/installing the guides or some pictures would be appreciated! Are the FRP panels you can buy from Lowes/Home Depot for $35 durable enough for the walls? Its a EZ-Hauler 7.5X18 with 5 ft V.
