I have one now courtesy of Camping World Raleigh (Garner) NC.
I told the sales manager that if the walk through upon delivery had been more thorough (ok the 5th RV I have purchased/owned I guess I thought I knew more than I did
) I would not have left the lot with it until it had a bypass so he told service to install one and winterize the unit with the antifreeze that I had brought to do this after I was shown the bypass location (unit was there for a few warranty repairs).
He was surprised the unit had no bypass since Fleetwood had sent me the plumbing schemetic showing there should be one. I guess Fleetwood does not include this unless the ordering dealer does not specify one.
Anyway Camping world looked after the bypass and I paid the winterization fee and supplied the antifreeze as I had purchased the antifreeze intending to do it myself because of the sudden unseasonable temps.
I know some posters here have not been satisfied with the Camping World 'experience' but I really have no complaints except I may have paid a little too much for my unit as I was 'underwater' when I traded my fiver but I got it done
