What is the dimension of the bracket base. I'm going to attach with 3M tape and need to know what width tape to get.

It doesn't allow you to attach a pic, which I put the dimensions. If you go to the Amazon page with the brackets available -- I bought the one on the left ($8.99). Longest side 2 3/8" Shorter sides 1 1/4" and Shortest Step-down section 5/8" Hope this helps.

What do you use for glue to hold to rv roof

I did not use the glue on mounting system I used the Z-brackets and sheet metal screws that came with the kit. I have read that others use AP Products 017-90916 Sikaflex-252, Black to glue down that bracketing system. I used that product to mount the cable entry fixture HQST Cable Entry Housing Mount for RV, Boats, Caravans, Marine, Cable Entry Gland and it seems pretty strong. Hope this helps. Jim

The ad states '4 sets', but i only see 4 z brackets. is each individual z bracket called a 'set', or are there 16 z brackets?

I received exactly what is shown in the picture. 4 Z brackets. Enough to mount one panel.

Any idea how I can get tilt on my solar panel with these?

You can"t with those. They are designed to lay flat on a roof. Now if your roof had a pitch to it the panel would have some tilt to it. There are tilt brackets out there for sale. I put 2 on top a flat roof on my houseboat and they have no trouble keeping 2 batteries charged. I am installing a wind generator a little later this spring to support the batteries at night with the usual wind we get on the lake.
