I opted for the 4800 but haven't mounted it yet. I haven't decided how to position it. For those that have mounted a 4800, if it you were to do it again would you mount it so that it opens to the back or to the side? Would you slide it all the way forward or closer to the taillight?
I have a Milwaukee Packout custom mount system (as in I made the retaining latch myself, and put packout feet on my 4800 case). In a move that has at least two actions that Milwaukee says not to do, it's mounted so it opens to the rear and I think it's perfect. My reasons are:
1) I can stand behind the bike with it on the center stand and easily access things. On the side stand it's not that big of an issue either, it tilts to the side.
2) If I have it open to the side, I can see myself dropping shit "under" the bike when it's on the kickstand (thus making it less easy to access when I'm wearing a helmet which I will inevitably bonk on the bike), or into the exhaust area when standing on the other side.
3) For some reason I feel like I often have better illumination when it's like this at night in an unlit environment. I don't know why, but it might be the rear light reflecting off my gear and into the case.
4) When I reach back to check the latches are closed, I find it easier to check the back of the box than the side. I also removed the two side latches as I wasn't using them.
5) I drilled a hole and added a port for SAE charging within the case. I feel this is possible to do with the case mounted sideways, but it's not as easy, or interferes with how low my jacket hangs.
6) As I get off the bike, I reach over, flip the latch that holds it into the packout system, then as I'm walking away push the case forward (towards where the rider would sit) and up. And that means it's super easy for me to make everything click into place. It also ejects TOWARDS the rider, so if I forget to latch it in theory it should smack me in the back instead of just ejecting and falling on the road without me knowing.
Here's a post with the position of the case. Disclaimer disclaimer, if you decide to do this do it at your own risk, but it works pretty well and I would do it again.
