Diesel --- front engine -vs- rear engine

I would seem to me that if one wanted a diesel the normal DP makes the most sense if for no other reason, the available selection. The shear quantity of units on the market virtually assure a prospective buyer of finding what they like at almost any price point from $30K to $3,000,000.

I've never even seen a front engine diesel RV in person. Just some pictures that weren't very impressive so certainly can not comment on performance, layout, etc.

I'm sure there are some perceived advantages with the front engine just don't know if they are important.
