I bought a propex heater HS2000. I was going to put it under the back seat but there's not enough room there now as we decided to put the LPG tank there.
Looks like we're gonna have to use the cupboard where we currently store the portapotti (see image below) and make or buy a buddy seat that can store the portapotti too..... unless we can find somewher else to fit it? Any suggestions welcome.

One idea was to install it just behind the passenger's seat as show below? I would box it in so it doesn't get damaged. Not sure whether there's clear space below for the exhaust outlet. I've got a feeling the underslung water tank will be in the way.

I assume the exhaust outlet has to go out through the floor/chassis of the vehicle?
Does anyone else store their portapotti in a buddy seat? Does that work well?
Cheers,
Tim.
PS. It's an Autosleeper Hightop.
