This coach IS NOT your ordinary 2012 Mountain Aire. It is loaded with numerous aftermarket modifications, always garage kept, and meticulously maintained. If something didn't work correctly, it was fixed the right way. New or almost new modifications include: (1) 800Ah of fully usable lithium house batteries (boondock for a week, a $10,000 value); (2) HWH Active Air Suspension System (look it up as it's unbelievable and I won't own another coach without it, a $12,000 value); (3) New, never used, professionally installed upholstery throughout (no more flaking common for years in Newmar models, a $10,000 value); (4) 36" Blackstone Griddle mounted on pullout tray; (5) All new larger screen, thin bezel, Samsung Smart TVs throughout; (6) Alpine iLX-107 Wireless Apple CarPlay Stereo System; (7) Fresh Water and Sewer Rinse ReelCraft 35' Hose Reals; (8) Half bath Thetford electric macerating toilet to match the rear bath; (9) HWH Air Leveling System to use when you don't want to use the HWH hydraulic leveling jacks; (10) Re-engineered Kwikee Electric Entry Step; (11) Sani-Con Turbo 400 Sewage Evacuation System; (12) King Size Purple Mattress (Still have the Sleep Number System); (13) Interior LED light bulbs throughout; and (14) Professionally installed diesel engine upgrade to run cooler and pull more HP (test show around 50hp extra, a $4000 value). This coach has a Cummins ISL 450 HP engine with Freightliner's XCR chassis.
