I have a bottle jack (I believe mine is eight ton; it's helpful to go a bit above the minimally required rating as it makes it less effort to pump up) and a harbor freight breaker bar and appropriate sockets/extensions. The lugnut torque for the Ford E-series dually chassis are 140 ft-lbs, and I understand from some quick googling that the sprinter chassis is basically the same (assuming steel wheels). That is not terribly difficult to manage with a decent breaker bar or lug wrench.
There are low-profile, double extension bottle jacks that some say are helpful for fitting under the vehicle with a flat tire. My jack is a single-extension model, but has a screw extension at the top of the ram and so a fairly low profile, low enough that I think it will be fine in the event of a completely flat tire. Thankfully I haven't had to test that part out (yet).
You likely already know this, but standard AAA coverage doesn't apply to RVs; you need AAA Plus (or Premier) with the added RV coverage option.
