2023 Newmar London Aire 4551

The London Aire 4551 is one of Newmar's flagship diesel pushers, and at under 12,000 miles with an asking price nearly $280,000 below MSRP, this one is worth a serious look. Built on a Spartan chassis with Freightliner running gear, it carries the kind of structural integrity and road manners you'd expect from a true luxury coach — solid, quiet, and planted on the highway.

The rear bath layout gives you a full private bathroom in back, plus a half bath up front so you're not routing guests through the bedroom — a genuinely smart arrangement for extended living. Newmar's construction reputation backs this up: tight fits, quality cabinetry, and the kind of finish work that holds up over years of use.

If you're seriously considering full-timing or extended travel in a diesel pusher, the London Aire tier is where comfort stops being a compromise. This one is sitting at RV Select in Seffner, FL — easy to get to and worth the trip to walk through in person.
