A thought occurred to me while I was cleaning out the insane piles of dirt under the floors... Since I now have all of the air lines, etc. exposed, is there any maintenance I should consider doing before I put the new sub-floor in? (replacing air lines, checking fittings, etc.). If doing it the easy way now can save hours of labor later...
Pretty rare to hear of trouble in the tunnel.
Give it all the once over with a critical eye, and leave the sleeping dogs alone?
Now is a great time to run that big conduit with extra wires, front to back, and into each bay, for all your future electrical needs.
Happy coaching!

I'm not so much thinking about the tunnel as the area on the mid-to-rear sides over the fuel tank and wheel wells: air lines, fuel lines/connections, etc. Oddly enough, the tunnel on the J is fairly accessible from the bottom side.
And yes, I have two HUGE air returns. Left side will carry electrical and right side will carry plumbing.
Maybe spray some soapy water on all the air line fittings. I've found a few of mine that needed a 1/4 turn or so.
The tunnel in our 4905 is fairly accessible too, but once you start installing tanks, generator, etc, access is much more difficult, especially as you age and have to do contortions to get to it. Btdt.
While the floor was up during my build I ran Conduit from one end to the other and installed most of the house wiring that I knew I would need terminating where the outlets would go and where the load center and power wall would end up, and a couple of extra runs of wiring that I might need, and have used a few.
The one thing I wish I had installed while the floor was up is the Fuel lines from the Main Tank to the generator, I did get them installed, but it would have been a much cleaner and more direct if I had done it while the floor was up.
