I think the build time may average around four months--but it obviously can vary some depending on specific options, time of year, and general shop workload. The options that may be completed elsewhere besides Phoenix (frame lengthening, liquid springs, leveling system, paint, etc) are also dependent on variables in those other shops.
I see that Free2RV's unit (previous post) took about 3 months and 11 days from order to pickup. Another recent build that I know about took 4 months and 7 days from order to pickup. My own build extended longer, a total of 5 months and 5 days order to pickup--but that included the holiday seasons when I'm sure there is additional lost time.
I didn't request or receive photos during my build, but I know that one that was recently completed did get photos; I think the Camper's Inn representative at Phoenix was the POC for those.
All the best, Mike
