Considering that we are in the midst of a nationwide pandemic...
Public restrooms are at the top of the list of disease vectors.
Even without our current situation you are going to wish you had a bathroom...
The first time a porta potty blows up in your faceup will be converted for life !
I quit truck camping and made the leap back to RVs and to my Casita
Spirit 17 for the very reason of our current health situation.
Being a camp host veteran...believe me you dont want to use Campground facilities now !
And yes you will need 2500-3000lb towing capacity with the 16' trailers....
I would recommend Toyota Tacoma as the best small tow vehicle on the road.
The small SUVs can also do the job.
The issue is not having enough power to get moving...its having enough of a vehicle to stop safely !
