I flew up to Provo to check out Moby1 about a month ago. We spent about half a day at their shop, and also visited their frame and suspension manufacture's facility. We had given Moby1 a refundable deposit to hold a production spot for an XTR, contingent on our visit. If I recall correctly, we were number 7 on the production list. I pulled out of the deal because I wasn't comfortable Moby1 could meet our schedule. (which was delivery by March 2013)
At the time of our visit, Moby1 was in the very early stages of production for the XTR. Not what I would consider "production mode". IMHO, Moby1 is a small shop. (I only saw one employee plus Ashley- that includes front office and production) In late September, Ashley's plan was to be able to produce 1 trailer a month for the next couple months until he could hire more people. After that, he thought production would jump to several a month.
Ashley's communication was always prompt and courteous. I would highly recommend making the trip to Utah to check out the trailer, and the facility, for yourself. Nothing beats first hand knowledge!
