After looking at prices I decided to do some trailer guide-ons myself. Used mostly scrap metal for the base, attached to the trailer with square U bolts (don't like to drill into trailers). The U bolt kits (both sides) cost me $30 at trailer dealer, and 1 1/4 PVC was about $8 at Lowes. I pinned everything beyond the base so it can be disassembled.

I added one up front, attached to the winch mount, to indicate distance to the bow stop. This one has REALLY come in handy.
