I'd suspect you won't be able to do so with a single axle. (assuming the coach you have is the one in your profile photo).>
It (toting a golf cart or similar weight) will mandate a tag axle if you want to go with a hyd. lift like the Hydralift.
As to a top down photo, I don't have one but the folding option you refer to is only for storage (when storing the coach) and not when using it. (cannot drive the coach if the lift unloaded and is in the stored position if that makes sense). We've never folded ours as we have enough space in our storage building. The lift we have is one of Hydralift's special build HLA platform lifts that was designed for the Garia 2+2 Low Speed Vehicle we carry (1200 lbs + lift weight of 700 lbs) and this it is not their standard lift. It has much heavier capacity hyd. rams, pump and is made with strongly allow materials.
Thinking about getting Hydralift for golf cart and being told that adding the folding option is dangerous. Do you have any top down pictures of your custom lift, seems like it didn't add much to the stock Hydralift, but I can't tell from the picture on the site.
