@steve, yes indeed , nothing to reference too ... that was actually the intention more or less

, only the fence give a clue .
@luvbus, yes I'm planning the hagglund , all parts are in , designs are ready but i cannot find 50wheels rubber with ball bearing for an affordable price ... cheapest i've found where 7euro a piece ; that's still 350 without shipment
hence we do plan other build in the mean time, patient can save you a lot of money , maybe i find a bulk of wheels in the junk yard one of these weeks .
I'm still fighting the truck's controller,I had a chat with a friend and these salvaged controllers come from a factory robot wagon, they where designed to pull up slow and stall if anything was blocking it ...hence the uphill issues .
w'll see , it rolls so tuning can be done in a later time.
cheers,
Luc
