My solid must haves would be: vent (fan equipped), solar array (min 300-400 watts), Li battery pack (200ah min)/controller, roof rack with built in ladder, 5-10 gal water tanks (1 fresh, 1 gray), 12VDC water pump, simple counter/catch basin, marine toilet and 2000w generator.

Perfect! Thanks so much for all the wonderful advice.

Have fun - easy, incremental steps during the summer will make for an enjoyable, manageable project.

Btw, the absolute go-to solar RV vendor is AM Solar. Tons of people drive there ie make a road trip out of it. They also have a list of subcontractors they've trained and rely upon in different parts of the country.

IMO, getting the 12VDC solar/battery system in place and under control is the #1 priority.
