Hey, gang

Thanks again for all the suggestions, extremely useful!

Here is what I have decided:

1. I will replace the existing 2 TV screens located in the airbag section with an original airbag (got one from e-bay for $200), so the battery charge hopefully stops leaking

2. Will check why the left door does not pop (hopefully, will be able to find a shop dealing with these types of issues in Chicago area..)

3. Will install the Back Up Button - thanks Knigh2s! "Two of these can be easily installed in the rear fenderwell on the drivers side" - so I need to order 2 of those?
Also, item description says "Even in the event that your car or truck's battery dies, if you mount the S7 in an elliptical hole you'll be able apply a twelve volt battery directly to the S7's terminals to activate your solenoids", so I guess I dont need to buy the "Autoloc Deluxe Emergancy Release Kit"?

4. Will install a very small 12volt battery (thanks, Rene!).. any suggestions on which one to buy?

5. Buying new doors for $1,000 sounds a bit expensive at the moment.. But I will be happy to swap if anyone is interested (e.g., when we get together in Moab?).. Yes, the cladding is painted, so it will need to be swapped backwards.. I will post pictures in later to see if anyone is interested..

Thanks a lot again, guys!
