Welcome to the forum Ligedy. Boy, you sure have done your homework on options, that is some list.
1. I can't help with full height vans, never pulled one
2. My van sits on a slope in its shed to the point where I can't level it but it is fine. Maybe if you want to run the fridge while parked it may give a problem. Just make sure the wheels are well chocked.
3. Phone as many dealers as you can and don't restrict yourself to Queensland. A lot of members (me included) went interstate for their purchase with great savings.
4. The answer will have to come from some one with that type of van
Good luck with the purchase.
