A lot of stuff in 20" AWP Tool bag (got it at Loews, similar to this one but 20": http://www.lowes.com/pd_351940-1492-1L-22418_0__?productId=3464260&Ntt=awp&Ns=p_product_p rice|1&pl=1¤tURL=%2Fpl__0__s%3FNtt%3Dawp%26N s%3Dp_product_price%7C1&facetInfo=
). This bag doesn't slide around but I also have Jeep rubber mat in the luggage compartment, so pretty much nothing slides around.
One tool I just ordered is 18-25" extendable breaking bar:
- I recently had a flat tire and the bar that comes with the jack was useless - I couldn't get lug nuts to move, had to call for roadside assistance.
Another thing I just ordered and will carry in the tool bag is rubber mallet (a friend removed all lug nuts but wheel wouldn't budge. Called roadside assistance and all it took was 1 whack with the rubber mallet).
I also purchased some sockets with 1/2" drive size (metric and SAE) and torque wrench that I will keep at home (http://www.amazon.com/Titan-23150-Ad...9429663&sr=1-1
I also carry some replacement fuses, air compressor, jumper cables and a bunch of other hand tools (pliers, screwdrivers, etc.)
