A Boxer Engine In A Class C??? Yes/No?

During WWII, German bombers would go 6,000 miles to Brazil with these motors and at that time, no other airplane could achieve that! And remember the Gatling guns the North had in the Civil War, well the A-10 Warthog jet uses Gatling guns as did the attack Choppers in Viet Nam and present day military. Years ago I spoke about how gas Class A's would get bigger with heavier chassis, bigger motors, and transmissions like the Allison 1000 and that happened. As a matter of fact, Damon & Newmar have class A's (Gas) today that are almost 40' long and back then everyone thought I was nuts! Back in 1990 we owned a 3/4 ton Suburban that got 25 MPG on the highway cruising at 70 MPH. It was powered by a Gale Banks 6.2L TD, with 3.42 rear end, and the TH400 trans was mated to a Gear/Vendor transmission, thus reducing the engine speed by 20%. Neighbors thought I had a gas hog, but I could drive that Suburban 600 miles to N.J. and when I got there, still had a 1/4 tank of fuel left! Anyway, I'm very excited about the future and new engine technology for all of us campers!
