Gasser guys and gals ...why not a diesel ?

Diesels cost more and cost more to maintain. Anyone that says different is spinning it. I do DIY and spend about $500 per year on supplies only. And not talking about tires or house batteries. Replaced starter batteries (2) this spring @ about $125 each, gas coaches have one battery. Fluids & filters (not including air filter) for ISL & 10K genny about $350 every year alone. Add def filters @ $50 each & air filter $150 each which I do every two years. Air dryer element $60 every 3 years. I've had to replace a air bag already. Many other ticky tack expenses also. Maybe I'm not the most careful shopper for my parts so others may do better sourcing. But a diesel simply costs more to maintain than a gas coach period. Also my ISL is not a large engine I had slightly higher costs with the C12 in my last coach. Many DP owners are not DIYers & spend one heck of a lot more than $500 per year. I'm just now replacing the OE house batts (8 230 ahc flooded). I don't need to muddy the conversation with that but many diesels come with larger battery banks than gas units.
