Our appointment time kept changing because the neighboring RV wanted additional services and TYDD accommodated them. I didn't mind the changes because I was home all day anyway but someone else may not have been able to do that.
As for the work, excellent! We had them wash our 40ft 5th wheel. Yay! Windows clean again! North Carolina mud gone! Coach looks nice and really needs waxing but it was not in our budget this time.
Would have them do it again when we are back in the area.
