This kit rides in my car’s trunk all the time. I also keep a fleece blanket, 6x8’ tarp, and rain pants and jacket there as well. In my car I have my ham radio, digital scanner, GPS’s and assorted other stuff such as another FAK, 2 D cell Maglite, shovel, Gerber multi-tool, Life Hammer and fire extinguisher. What can I say, I’m a gear freak.

Whole package weighs about 25 pounds. The pack itself is quite nice, with chest and waist straps, compression straps, MOLLE attachment points, etc. Was $30 at ebags.com.
Most items are packaged together by function. Everything is in waterproof packaging. 
I’ve switched from regular ziplock bags to Reynold’s vacuum ziplocks. Available in quart and gallon sizes you use a handlheld, battery powered vacuum device to evacuate the air from the bag once you’ve zipped it closed. Works pretty darn well and since the bags are reusable you can open them up, remove items, seal them up and re-do the vacuum. Wouldn’t take the vacuum device with me as part of the BOB, but it would be easy to store in your camper or RV.  
Here's a link to their product page. * The kite is an alternate signal/location device, could also be used for fishing or just a fun way to kill time while stranded. Bike gloves protect my hands from the string.
