Hey folks,this is ken Wilkinson, several years back, I owned and operated an RV rental company so ,i have a good idea what holds up and is quality.
I been very  pleased with the quality and durability of the tiffan allegro breeze. It has never been rented.
It is a non smoker and we have no pets( a few chickens in back yard)
i have done most of the maintenence and believe it is in great shape.
if we can answer and questions please text or email
no DEF required in the diesel fuel
