Thought id post my cabinets/galley layout as it may be of some use for ideas.
My pics are from a crappy phone cam so sorry!
Can I just say first my woodworking skills are far from great, so I mainly used pocket hole screw method construction using 2x1 framing and 1/8 ply for the fronts. The doors are 3/4 ply.
I found this video on youtube of a camper rental company here in the UK and really liked their rough galley layout so I based mine on it.
http://www.youtube.com/watch?v=P2tYeEGe0AI My skills and budget didnt stretch to this (formica in the UK is expensive) so ive recreated what I can using ply and similar materials. My main changes were to fit a gap in the middle to fit my fridge/can machine and use the side parts for interior storage rather than 'bins' for galley kit. My advantage is though I have a very large worktop space now for hobs/cooking
Here is my galley
The worktop is 9mm kitchen splashback, the cupboards are all 2x1 pocket hole framework, The two side parts at the top really are the inside cupboards, but ive utilised the top section to hold tins/plates etc and the bottoms fit my gas burner and electric hotplate when not in use. The sink is a dog bowl! The lower cupboards are big enough to house a 55amp battery and a small water tank in the other. The sink waste drains to a pipe below the trailer itself.
The cupboards inside are built using the same framework method to keep it light, 1/8 ply front and 2x1 framing.
The cupboards inside aren't pretty but show the depth created, using the galley bits. The cupboards are roughly 1x1ft and about 18 inches deep. It also has a central section for the TV, the top section houses two cubby holes and the central upper holds my 240/12v power unit with battery charger. There are also 2 UK 240v power sockets.
They are quite lightweight, if I could do it again, id probs make lighter cupboard doors. They are 3/4 ply and I could have made 2x1 framing, but I was originally afraid that theyd break when I hammered the molding round them.
Pocket hole screw jigs kick ass, mine was the cheap kreg basic one here
made them all fine!
Hope these help someone for ideas, TNTTT have been awesome for info for me!
