Only 400lbs, could be pulled by a smart car lol. $1500 as is, $3500 completed. I can customize it and finish it out how ever you like. I made the entire structure out of reclaimed scrap building material from construction sites, saved it from going to a landfill. I would like to continue the build with a conscious approach to sourcing material in an eco friendly way. This will be the first of many rv’s/campers that I want to build in this way, helping to create eco friendly campers for adventures at an affordable price. Your purchase will be the start to making this a reality! -The windows are insulated glass -the trailer is from harbor freight (1200lb capacity) -all construction is done with screws -can be sold without the trailer for a price reduction of $350
