I arrived at a wheel to blend the top and bottom and not have to fashion a fascia. Wheels are also practical and I have 4 from a wagon whose steering is broken. I thought I was at a no-cost DIY until I found a wheel not holding air. I replaced them at Northern Tools @ $4.99 a piece, plus tax–not bad… I think we have a cool looking buggy that will protect my CamRanger Rig from rain or snow. Next–clean-up.
