hi i wondered if anyone out there could help, ive purchased a bmw 535i touring 1991,  i climb munroes  in scotland and  to continue to check them off the list ive a bit of travelling to each start point, so hence my querie ive bought the bmw which i propose to convert the rear of the car into some sort of sleeping accomodation with the rear seats removed, ply floor in and carpeted ive got a space of 2020 l x 1450 w x 780 h , not massive but comfy enough for a couple of nights, ive a double opening sunroof so the whole of the roof area slides back, ive a blackout limo tint to the rear windows of the car and black out curtain between this area and the front seats, and a carnopy canopy to the rear which i set up the kitchen area and enough for a seat, resourceful eh! im only 5'10'' so i can sleep the length on a bed area on say 900 or 1000mm wide and propose to build in a storage area the full length  and height with the remaining 450mm or so also locating a water tank within as well all the above is fine i can undertake that, but id like to run some power to the rear area, install a 2nd leisure battery (main car battery under rear seat access will be left, theres space to locate another next to it) i would be hoping to install a couple of lights, small dvd player and screen, radio, maybe have a couple cigar type sockets that i could use to run a small kettle or fan in hot weather and i havnt thought of heating in poor conditions maybe thats not feasible on an install as small as this? i plan to keep the car for the forseeible future and would like as profesional job on it as possible and im as well doing it all during conversion, i see you can buy a zig unit panel that would appear to allow you to wire it all back to it and use it as the control panel. any advice on what to do or even what not to do all info would be appreciated im quite handy and will do the work as far as possible myself, the above has probably been answered before but its new to me. regards ally
