we did the fence post mod over the propane tank - you have to angle it back towards the battery compartment/entry stairs to make it fit. We used some extra-strength zip ties to hook it one.
Have to say the "poop slide" as we fondly refer to it - is one of my favorite modifications, easy to access yet out of the way and doesn't take up any additional room in our bins. I think we spent maybe $80 all in - have to make sure to get the 5x5 fencepost and the the correct size gutter. Plus we had to get a rivet gun (and I've had fun with that one on some other projects too!) so that's been nice.
I'll see if I can find some photos tonight -
