Hey Greg,
Doing the same thing in my camper trailer (1 drawer to sit behind the tailgate kitchen) at the mo and have so far gotten tons of info off myswaggers, so you're in a good place.
I tossed up between DIY and buying Drifta initially and comparing cost VS quality but decided given that I've been doing mods on my kitchen already and had the wood (and my woodworking skills weren't too bad), I could do it myself.
dg3754 has done his own which I quite like and will use as a starting point for mine. He goes into a bit of detail in post 19 and then later on in post 45 (answering my question re: more details). He also has the double draws at the front which I will definitely be doing.
http://www.myswag.org/index.php?topic=42598.0I've also did a google search on 'homemade ply drawers' and variations of that. Great thing about doing it in google search, you can see all the pics and if it's what you like, then click on the pic to go the the website etc. Found some awesome DIY jobs across a whole bunch of different forums this way.
Regarding how I'm going to do mine - I will use a mix of 9, 12 and 15 marine ply with 2 drawers at the front which will house the camp oven and an additional pantry box (and various other junk in the back
). I have a lip on my tailgate kitchen so an easy slide out won't work, so instead sussing ideas of creating a ramp or something similar between the trailer floor and kitchen above to make it rise nicely. Not decided on sliders yet - either blue boat runners from whitfords or bcf.
Good luck!
