HR built a decent unit on the roadmaster chassis which is what your ambassador is....your factory support is alive and well and so is their service center along with plenty of places (aka Allicance Coach) which are all ex Monaco people...if this is new, it backed by ASV which purchased the Monaco RV LLC from Navistar...depending if used/new etc, you have no worries...if new, the tires/batteries have got 2 years of lot rot so use that as a negotiating tool..Batteries might need replacement if allowed to go stone dead on a dealers'lot.
