Darn it, Mama, I was hoping you wouldn't say that, now I gotta go back and remember stuff.
This is a recap of what I had posted awhile ago ...
* * * *
As to never leaving well-enough alone, in no particular order here's a list of changes/upgrades (so far):
1) KVH In-Motion R5 Satellite (BTW: an external DC power-supply worked wonders to keep it tracking correctly!).
2) 2 XM radios, one wired thru the big HTIB stereo and one thru the dash radio.
3) Jotto-Desk for the laptop and DeLorme map-software.
4) SilverLeaf VMSpc engine-monitor.
5) Vena AC/DC power monitor panel.
6) Progressive Industries 50A surge protector.
7) BrakeSwitch engine-exhaust braking switch.
8) Gen-Turi generator exhaust chimney.
9) Installed a full-coach water-filter system.
10) Added multiple wireless thermometers & sensors to monitor outside & inside temperatures at various locations.
11) Added a small fan in overhead stereo compartment above driver head to circulate and exhaust hot air (satellite-receiver added a lot of extra heat).
12) Routed the Satellite receiver audio/video through the HTIB receiver for much better sound and picture.
13) Reversed most of the switches in the coach (ie, you'd flip a switch ˜up' to turn the light off).
14) Re-mounted the rear-camera monitor up about 4-6 inches, so's I won't have to peek thru the steering-wheel.
15) Took out the bed under the couch and replaced it with additional storage space.
16) Routed previously blocked-off under-couch heater vent to exhaust behind driver seat now.
17) Removed all window frames and glued in thin pipe-insulation between window frame and wall, to eliminate squeaking/rubbing while underway.
18) Added a small shelf in Inverter compartment to store portable satellite-dish and tripod.
19) Added hasps/locks on the outside compartment-door directly behind the water-heater and installed a thin plywood layer over holding tanks, for small/light item storage (such as the generator Gen-Turi carry-case).
20) Installed the remote-keylock system LED indicator light on a windshield pillar.
21) Reversed both the power hose-reel and cord-reel, so's they wind up OVER the reel and not under (talked to the guys at TDI Products and they said they were installed backwards initially).
22) Sealed a major water leak at the right-rear corner (which was causing water to pour in under the washer-dryer and onto the Inverter).
23) Added 2 shelves in the storage-bay on road-side.
24) Moved the Dometic Comfort-Control Panel about a foot lower, so we could read it without standing on tippy-toes.
25) Replaced the 2 over-bed dim lights with directional lights for reading.
26) Cleaned up all the post-construction leftovers, such as leftover screws & debris behind couch, etc (I'm a stickler for details like that).
27) There's probably alot more, but that's all I can remember right now.
Still to do:
1) Trace a pesky 12VDC intermittent wiring-short in the Atrium. (Update: done!)
2) Add a toad tire-pressure monitor system. (Update: done!)
3) Wax it (Yikes!). (update: done, but I paid to have it done

)
4) I've got more things I want, but this is all I'm willing to admit for the time-being. (yeah right!)
As-yet unresolved concerns/problems:
1) Like mentioned elsewhere, the engine-gauges may need some work. (still to do)
2) Refrigerator and Freezer doors hit each other and/or trim pieces when opened/closed. (Update: done! frig was replaced!

)
3) Weather-stripping around exterior of Bathroom & Atrium slide-outs is pulling loose. ((Update: done!)
* * * * *
Since all that, here's a few more:
1) Added See-Level gauge system.
2) Added CB Radio (why???? dunno)
3) Added SMI AirForceOne braking system)
4) Replaced big chair in Atrium with a computer desk.
5) Added cellphone antenna
6) Wedged a plastic storage box over the fuel-tank on one side to store wood-blocks.
7) Re-calibrated the fuel-gauge.
8) Made a plexiglas "storm door" over the screen door.
9) Replaced short generator fuel pickup-tube with longer one.
10) Put under-frig louvered door on hinges and made a shelf.
11) Put louvered door on hinges and made a shelf under flip-out counter-top next to sink.
Like I said, I'll try to remember more.
