I need a travel desk for my writing

I've decided that I need a travel desk for my writing. I've had a few over the years, but I want to design this one to fit my needs, not get what fit someone else's needs.

Although I would not mind having a antique travel desk. lol

Anyway, I want to be able to stockpile it with what I need, and then toss it at a moment's notice in the car or on the back of my ATV and take off cruising with my noveling stuff along for the ride.

Still plotting the basics, I'll let you know what I end up with.
