Please forgive this naive question

I have a C reg Caravelle auto sleeper,it only has the main battery that I use an inverter for when camping with no hook up.Is it possible to fit a ;leisure battery?

[Red Westie]

YES!
The common setup is to install a second 'leisure battery' and wire it to the existing battery through a split charge relay.
On camp only use power from the new leisure battery and because it is wired through a relay the main 'starter' battery will remain fully charged and untouched, ready for starting the engine.

You may be able to fit a second battery under the oposite seat (if petrol engined) or a suitable cupboard or under bed compartment.

... and the wiring diagram to fit Autosleeper aux batts is, yes , you guessed it ...in the wiki
there are aux batteries that fit under the seat, a UK code 096 will fit or if you want a leisure battery that fits, then a search will reveal the company that sells them.
