What's wrong with bumper sewer hose storage???

[sacmarata]

I've read about and seen some really cool ideas for storing the slinky but still can't figure out why folks won't use the rear bumper storage (If available)?

I know the factory caps fall off and the hose can easily fall out but wouldn't it be a lot easier and cheaper to make a good cap with latches/hinges/fasteners on it for the existing bumper than it is to fabricate a completely new device to hold the sewer hose?

Help me out. I'm likely improving the factory bumper caps on mine this week. Have I missed something? Is there a reason not to?

I've even seen square PVC pipe the same dimensions as the rear bumper mounted right on top of the rear bumper??? WHY?

I store mine in the bumper and even found a bumper cap that has a hinged door on in. I had to use self-tapping metal screws to get it to stay on but it works well. One negative to storing the stinky slinky in there is that it may rust out the bumper tube after a while.
