Using this and other RV plus HDT forums maybe a network of HDT owners/drivers can be created to help each other out with this problem for a hefty fee maybe.
If you pay yourself the tow truck outfits may tow you from further to reach places which would be my offer if I break down in my Dodge Ram further from the paved road once the operator arrives onsite and we cut out AAA or I may not even call AAA. I was stuck in a sandy beach area next to a lake and the park ranger towed me out and I cancelled the AAA service call. I did tell them I was stuck in the sand away from road.
No ideal solutions for any of us it would seem. Maybe someone here has actual experience with this challenge.
