Here's what I did with my 42 gallon tote on our previous Fleetwood Prowler. Mounted crosswise, one side hinged down, allowing the tank to roll out the other side. Didn't have to remove the long handle, just rotated it 90 degrees forward, allowing the two pneumatic front wheels on the tote to drop down into slots, "locking" the tote in place. Then lift up, attach clasp, and off you go. Bear in mind you could only "stow" the tank when empty, NOT when full! You couldn't even see it from outside unless you got down on your hands and knees! Hopefully the attachment came through!
