How to change out the engine on an RV/Motorhome?

[Coley]

Anyone know what it takes or 'how to do it' to change out/replace the engine on a 'C' series motorhome/RV?
That is the kind of RV that has the standard (GM) 'van' front end only and then a big full body camper shell attached and integrated into it.

Now, I know that if it was 'just' a regular van you would do it from/through the sliding side door. However an RV does not necessarily have that size of door in that location....plus its interior rv stuff might be in the way?

Is this someone done through the front end, thus removing the rad support, bumpers, hood, etc...hmmm? or remove the passenger seat and go through the passenger door? .....or?

...just curious if anyone has any history with this, witnessed it or actually done it.
