Opinions on diesel vs. gasoline

Had several class C with the V10 engine, the engines never gave us any problems, But, they were noisy, lacked power going up hills, no room between the seats because of the dog house, put a lot of extra heat in the cab, always down shifting. Now we have a Super C, a Thor Omni XG32 on the Ford F550 cab and chassis with 6.7L diesel, It drives and handles so much better than the van chassis, it's much quieter, plenty of room between the seats, no heat in the cab from the engine, rarely down shifts and goes up and down hill's or mountains with ease.
Would not own a gasser again, night and day difference.
