Now you can bring your neighbor friends along on trips since this motorhome can sleep up to six people each night.

You and your spouse will have the master bedroom all to yourselves with a slide out king bed, a dresser, and two wardrobes. And check out the full rear bath with tons of storage space and a shower with a seat! Breakfast can be made on the three burner cooktop or in the 30" stainless steel convection microwave, and the milk can go back in the 19.7 Whirlpool refrigerator. And since this model includes a full-wall slide, you won't have to worry about being cramped on space!

 

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 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.
