I will be able to measure actual dimensions next week, in the meantime you may be aware that Vans has downloadable CAD 3-views of all the RVs. The scaling is accurate so you can use a CAD program to measure the dimensions.
Also, when the time comes to shift the fuselage it is easy to take off the wheel spats, and you can use castoring bases to manoevre through an opening that is a bit narrower than the wheel base.
If you can make the door opening 8' that would certainly work.
