There is more to it than just adding a pellet burner or door shocks.
When you are in a chair, you are largely limited to reach, hence the issue with sinks (and the current ADA standards leave a lot to be desired) for instance, many disabled don't like the long reach over, as their sleeves get wet, now, instead of water, make that fire, and you can see, that the location and how the fire is arranged, as well as box depth is an issue.
Further, cleaning the unit is going to be an issue. Sure, you can always ask for help, but, true independence means being able to access all of the controls. Always the details...again, for instance, you could just put a small Backwoods onto a wheelchair friendly rack, but, when it comes time to add charcoal, or tend the fire, you are pulling that drawer out onto your lap, not exactly safe. When you are reaching up to tend food, you are reaching over hot coals, also a risk.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
