So mine took about 5 months, working off and on. I decided to do the foot box down below so I could have a couch set up and storage and drawers in the back. The inside foot box hatch doors turn into a table for inside while you have it in couch mode. I added a bluetooth fm radio and it is wired for 110 and 12 volt.
Lots of lights and a vent fan up top. Its got a harbor freight trailer and battery box. It also has an 80 watt solar set up thats portable. Im in Portland and it was only built to sell so if anyones interested Im putting it on craigslist soon, probably for around $8500.00
I live near Portland Oregon.
