Gas vs diesels

First, I will state that I have a 5er with a diesel truck. Diesel pusher MH from what I have observed aside from the engine, have air breaks, not hydraulic breaks. A whole different animal. A diesel engine while it is much more costly to maintain during oil changes, etc. might be more costly for repairs. My truck takes 18 qts of oil and filters are about 3x more expensive than if I had a gas engine. A big plus to the diesel..... If you are going to do heavy traveling and do a lot of climbing like the mountains out West, then a diesel will maintain your torque at high altitudes.
