At first glance it looked like this would be a good tent to attach to a SUV, either at the tailgate or side. But the height it only 5'2".
Looks like access from a wheel chair is good, but I wonder whether it can be setup while from the chair. Another question would be whether it can be setup on pavement, or whether it still needs stakes.
Increasingly campgrounds have one or more wheel-chair friendly sites. Often they are reserved for handicapped use, unless they are still unoccupied by some time in the evening. Most have a larger overhang at one end of the table, and a paved pad around the table.
Last time I passed through the North Cascades National Rec Area I noticed that some trails have accessiblity specs - details such as surface, minimum width, maximum grade, maximum side slope. One trail guide showed the grade range for different trail segments.
