The HD Deuce saddlebags are a rather permanent install, as you do have to install the brackets, and different rear turn signals, so the removal takes quite a bit of time to swap back and forth.
I ended up going a different route, and ended up going with the small HD backrest mounted roll bag (which is a Half Sac
www.coolsac.com) that I leave on most of the time, as yuo can see from my avator. From there, I also got a HD universal roller bag, which mounts very nicely on the back seat. I bungy them both together and it's quite solid. I can then mount a third small duffle on top of the half sac leaning against both as seen in the attached photo. I use that for my helmet or rain gear.
In this manner, I can pack a ton of stuff, and still break it all down in a matter of minutes. Works great, and the total cost was less than 1/2 of what the saddle bags would have cost with nothing near the hassle, and much more storage to boot. On the other hand, if you like the look of the saddlebags, you could add all of the above, and easily rival an Ultra with storage capacity. The saddle bags just aren't my thing.
