I plan to line the rear interior all over with compressed foam underlay then carpet it all for insulation (roof and sides,) then a few other bits and bobs to get her ready for my fishing/camping trips, like cutting some wells in the rear for storage boxes and make hinged lids for them, fit my generator in the back with a home-made exhaust to the outside, maybe the portaloo too, but probably not. Make curtains for behind the seats, the side windows and the rear end (my 110 is the commercial version but with side windows,) make some sort of sleeping platform, make an awning too, fit a hinged shelf on the rear door which will be used for a folding camp cooker and basin for washing up - I'm pretty much doing a camper type conversion.
Make and fit a cubby box which will be mounted around my Eberspacher heater with built-in easy accessible controls, try to make my Everspacher work by remote control to supplement/replace the current timer I have. I just have to work out how. My basic idea is to use a central locking remote which will trigger a relay. Once the relay is powered up by the remote, it will also power itself and therefore lock on. Then to switch it off when I arrive at work I will wire in a cut-out button to power it down. If this all works out ok I'll try to wire in a 2nd relay which will also de-activate it via the remote. Also, try to work out how to flash my indicators to visually confirm operation etc.
It'll probably take me most of the year to get everything done I want.
