I like how you have the spare tires mounted on the side. I would add on of these to fill the dead space inside the wheel.Here are some more photos of the Turtle taken before it left for Overland Expo. It does have cab-to-cabin access, however the interior is unfinished.
There will be better photos when everybody gets back from Expo. The scenery in the Southwest is much better for photos, at this point, that our "early spring" locations here in the Ozarks.
We'll work on keeping you posted.
