I have the Altrider rear rack and replacement rack for the rear seat. Also have Jesse bags with the 'narrow' option, removing the passenger grab rails. For my month long retirement ride in 2018, I took off the tail bag and made it one long continuous shelf , instead of a raised rear shelf for my Wolfman duffle long-ways, since cross-wise, I could not open the bags! Like this:
When I came back, I raised the rear rack again, got a small Pelican box and attached it to the shelf for my tools, tire repair stuff and pump, then stuffed the rain gear under the shelf in the little cubby, like this:
Decided to go back to a long, continuous shelf and combine everything in one box and discovered the Apache 3800 from Harbor Freight fit perfectly between the two cases, still allowing me to open them! It is a little more than twice as big as the smaller Pelican. It now looks like this:
And my Kreiga 30 L waterproof bag fits perfectly in front of the box and between the cases, still allowing access without removal!
The beauty of this new setup is that on another long trip, if I spend every 4th night or so in a motel, the Kreiga and my tank bag can go into the motel in one trip and everything else is locked and secured on the bike, avoiding two trips out to unload everything!
Now I just need to be able to escape to test it out!
