I am selling my motorhome and then I will be in the market for a van and trailer to convert. I would like to convert a small cargo trailer to tow. I am thinking about using the trailer to make the couple (van& trailer) more off-grid capable, with more water extra solar systems etc... I also really like the older Chevy vans like the g10s and g20s. I will want a 4x4. Thoughts/ advice?
