Yep, bought a HonWave when they 1st came out and couldnt find any wheels to fit because of the extended floor.
Ended up buying a C-Tug, strapped it on tight with a ratchet strap and it worked really well.
It only died when I got lazy and dragged the whole lot behind the Rangie down to the lake. Note to self, the plastic wheel bearings melt pretty fast when being towed at 20mph
