OP - Suggest you compare:
1) Newell to Prevost Based coaches
2) Newmar Upper End with Foretravel/Country Coach/Monaco/Etc. (Key here, is the upper lines of each...).
Otherwise most would consider this to be an apple to oranges comparison
Me personally? I would pick a budget range, and then compare the upper end of the food chain to budget vs livability and buy the unit that seemed to match this the best - regardless of model year. AS LONG AS IT WAS WELL MAINTAINED
! And had adequate documentation...
Fun place to be in, considering these units!
