Newmar London Aire Class A diesel motorhome 4551 highlights:

Full-Wall Slide
Hide-A-Bed Sofa
Three TV's
Large Pantry
Slide Out King Bed

Head out on an adventure to see the Grand Canyon, the Pacific ocean, or the Rocky Mountains in this luxurious motorhome. You will appreciate a spacious full rear bath with a shower with a seat, a wardrobe with sliding doors, plus two bath sinks for convenience! The half bath will be perfect if you are traveling with friends, and there is a master bedroom with plenty of storage space for your belongings. The chef of your group will be able to prepare meals each day on the three burner cooktop or in the stainless steel 30" convection microwave, and there is a hide-a-leaf dinette where you can enjoy your meal together and play a game of cards after it's all clean up!

The London Aire Class A diesel motorhome by Newmar starts with a Freightliner chassis with a tag axle and 605 HP, tire pressure monitoring on the tag axle chassis, aluminum wheels, and an electronic chassis information center in dash. There is also 5/8" foam insulation laminated in sidewalls and ceiling to ensure years of use. You will stay comfortable with the three 15M Penguin heat pump central air conditioners with remote control thermostat that will keep you warm during those cooler months. Each model includes super polished solid surface countertops, hardwood cabinets with raised panel doors, and many more luxuries. Some of the conveniences you are sure to appreciate are the central vacuum with a tool kit, the Aqua Miser shower system, and the air leveling control system for hassle-free setup.
