Just purchased and finished assembly of one those for myself
They are a nice shelter.
I will be making my own tow bar. As for a tow rope - just put 3/8" bolts through the molded in tow bar pockets and tie the ends of a rope to them.
I made my own wear bars from an 8' X 3 1/2" X 3/4" PVC trim board fro Lowes ($12.50 + the hardware) ripped on my table saw to 1 1/16" widths. Ended up with a spare. Worked good for me (it'll be nice if they actually wear well).
Not sure about the bench seat yet - it is nice enough but if I end up not liking it for some reason, I'll build a custom mount for a comfy, swivel, boat seat.
