Diemaster - glad your Mom and the your fur friend are doing better. You got the advise on the Tow/Haul for braking, try campgroundreviews.com to check campground reviews (most of the time they are spot on) and fire up the generator to run the roof ACs. We use GasBuddy to find timely refuel spots and if it isn't a Flying J we go to Google Maps to check out turning space.
Best advise - get back out there.
