Just bought one of these from Crazy Clarks' [the Warehouse has them too] for when on the road. Bending isn't too good with my breathing problem, so I won't have to bend over to put Angel in the 'van any more.
It folds.
$39.95, but I hink that price ended yesterday. A bit dearer now.
I actually have a brand new dog rampstill in carton which I've never used and will end up giving it away to someone. It's a heavy duty one and from memory cost about $90 several years go. I'm happy to give it to someonefor the cost of postage from WA.
You can get ramps like that for motorcycles, usually made of aluminium. Just thought you might like to know that in case you had a pet baby elephant that you were travelling with.
