Replacing rear furnace in 345 moho.

Hello! I had SERIOUS problems with my rear Furnace in our beloved "Bangles"! A propane leak, wherever.
I need to live in Bangles in Wintertime (Christmasmarketseason!), so a dependable furnace needs to be on board!
While i know, that the OEM "Duotherm" 25.000BTU is not very good to fix and parts not easy to get, i decided to change the entire furnace to something new. (SAFETY FIRST...!)

Has anybody any expirience about it?
Bangles is the "east-west" islandbed floorplan, there is a very small space under the drawer of the single door shirt cabinet only.
It appears to me, "Airstream" installed the furnace etc. first, then the cabinets...!
If REALLY this is the fact 😳, HOW do i de-install, without destroying the furniture????
Also, is there enough space to install a "Suburban" NT-20SQ between all these pipes for the holdingtank vents?

What about the outlet for Exhaust (fixed pipe now) and airintake (flexible Alu-hose)!? As far as i saw, the Suburban needs fixed conections to the outside.
See the outlet now:

I like to avoid body modifications for the furnacechange. This has bin made by one of the old owners, while they changed the front furnace in 1997 (Now SUBURBAN NT-30SP).
This unit is also "gone"...!😡
I will change this 1:1 by keeping the same unit.
But see, how ugly it looks outside:

Have a great sunday!!!!
