I want to produce a few sketches of a custom set-up for my 2000 T4R. I just want to place antennas on the outside, show my Yakima configuration on the roof, my RotoPax gas tanks, and maybe a few interior frame drawings to indicate how I'd modify the vehicle with some electronics, throw a satellite dish somewhere on it and a few solar panels... Some pretty crazy stuff, but I don't want to do it by hand.

I know that there are some incredible, detailed software platforms for doing this, but all I want is something simple. It doesn't need to be complex. just something that allows me to click/drag, choose from menus, etc. or something like that.

There may not be any dumbed-down programs/apps that will allow me to come up with configuration sketches quickly and easily, but I thought I'd ask!
