So, after all my extended project replacing the rear...everything, I took
it for a spin today before driving to Mansfield tomorrow. Everything worked
fine. It stops pretty darn well, though I still can’t lock the brakes.

I installed a vacuum pump similar to the one JimK sells to replace my leaky
JC4 and as long as it has power, I can’t run out of boost. It sucks from a
one-gallon vacuum reserve tank. But it ran and ran on Saturday when I
installed it, until I found that check valve in that tank not fully seated
and leaking. Maybe that JC4 pump wasn’t so leaky after all.

But here’s what happened today:

Macerator wouldn’t run. Turned the shaft with a screwdriver—that didn’t
help at first. Fried the fuse in the attempt. Finally got it to run, but it
does not start on every throw of the switch. I can live with that, or deal
with it in Mansfield.

Fantastic Fan would open but the fan wouldn’t blow. After much fiddling,
figured out it was the remote out of synch with the fan, and it was
thinking I had set the fan to a higher temperature than we had, and would
spin up the motor. Got that working.

Water tank wouldn’t drain. Bugs had built a mud nest in the drain pipe. Got
that fixed.

One of my two propane tanks has a leaky attachment. I used two 20-pound
portable tanks, so I switched to the other one. Fine for now.

Power Level air pump would turn on. Huh? That’s been working hard for the
last few weeks. Checked the fuse, which is an inline fuse to the main power
feed to a load-reduction relay. The fuse was actively burning up. Turned my
main kill switch off to stop the current. Cut that melted and fried fuse
holder out and replace it. Works fine now.

But the goofiest one came at the end of my test drive. About a mile from
home, on my bumpy dirt road, I suddenly heard a metallic dragging sound.
Stopped and circled the coach looking for some rear-suspension reaction rod
or brake part I had installed dragging on the ground. Nope. Then I saw
it—my lovely stainless steel air tank was dragging and held only by the two
air lines. The bracket was bolted to the bottom of the battery tray, and
the bolts had come loose and fallen out. I had to cut off the threaded rod
used on the bottom of the clamp because of rust, and then reassemble and
re-attach the bracket. That took an hour to fix.

Just a normal prep day for a trip. Sheesh.

Good news, though. No evidence of mice since I bought all the stainless
steel scrubbies in a five-state area and stuffed them into every possible
entrance point. We vacuumed up a thousand or two stink-bug carcasses, but
that’s normal.
