Answers to questions below:

1. It does come with a base/bolts. The base is rails with a quick release spring lever on each side. We mounted the rails on plywood for use in my Xterra, and that's currently how it is.

2. No idea how heavy it actually is. Let's just say that it's not bad to lift it up into a vehicle with 2 people if the drawers are out, but too heavy to do so if you don't remove the drawers.

3. It doesn't come with top rails. There is an about 0.75 inch lip around the top. I used to keep paper and a printer up there and they never came off.

4. There are some dividers. There are pictures below of the locked compartment and there are dividers in the large bottom drawer that you can configure how you'd like, I never used them.

5. The front of the unit is just aluminum.

6. Drawer dimensions (approximate inside dimensions): the upper 2 drawers on both sides including the locked drawer: 4.25" high x 8.75"wide x 27" deep. The 2nd drawer on the unit's left has 3 compartments. The top drawer on the left has compartments for syringes and needles.

Both side bottom drawers are 7.5" high

Both middle drawers are 12" wide.
