My first two rigs were gas - our third is a DP (as noted in my sig below)- once you go DP, you never go back!. The difference is like plain biscuits vs Double Chocolate Cake!!
My personal experience: a gasser needs more regular maintenance and the engine components are subject to more frequent failure / replacement (starter, generator,belts, etc) as gassers are mostly built on lighter frames.
A DP is usually built on a heavy-duty truck or bus chassis and the whole complex is much more robust - but the regular maintenance is still a MUST!! Oil change on a gasser at 6 months - about $50. Oil change on my DP each year - $250. (Shop rates are over $110 hour here, so labor is a big part of the cost - if you can DIY, the cost is MUCH less! (But at 79 years, I am happy to pay the labor cost.)
If you would like an extensive pre-purchase checklist for a DP, just send me a PM - I have a couple that may be of use to you.
I would argue that your information concerning the Ford F-53 RV chassis is old and incorrect. The Ford V-10 is one of the most reliable gas engines ever built. Oil change interval is 7,500 miles or ONCE a year. The oil can be changed at any Walmart with a large service bay.Major scheduled maintenance is at 100,000 mile intervals. The chassis itself is a heavy duty truck platform. The 2016 F-53 now has a more modern six speed transmission.
