Almost DIY camper trailer

[untraversed]

Anyone have any luck with building up an offroad camper from something similar to a Weeroll trailer? I was going to purchase one but the owner of the company informed me he's taking a break from building anymore due to an accident. Any similar alternatives out there? The prices were great and I've read excellent reviews ,so it's too bad that's no longer an option. I'm attaching a pic of what I'd hoped to start with...
Thanks for any information!!

Well, I'm feeling stupid now...can't delete the post but it turns out I was wrong about which manufacturer is temporarily out of business...but still I'd like to know about any experience anyone might have with Weeroll or any other similar brand. :)
