I do not think the OP is that unusual in waiting. We went hot and cold three different time over five years in our search for a RV. After the first time I kind of knew what I wanted but started from scratch each time because I had learned more and RVs change. I now have a Lazy Daze I got used. Each time i started from scratch I finished at the LD but a different floor plan. Once I knew what I wanted I could sit and wait and get the LD as I would have ordered it. Had I purchased new I would have had it made just like the one I have.
This is true with used and new units. I know that people wanting a new LD have to wait a good while for the unit to be built. Some RVs do not come off an assembly line but instead the company build them as demand requires. It is a different business plan and judging by how long LD has been in business a sound practice for a small volume outfit.
I really like the OP's Big Foot. Very nice rig.
