When I got my 72TW, I looked at what was needed, then spaced it out....you will find a few other items along the way
Mine had to be moved so tires and repacking bearing were first. That was to move it to a place where I could replace the axles.
Furnace- no way was I going to trust a 35 year old light duty heat exchanger. I bought a furnace that was a year old from someone putting in a larger one. The original furnace was recalled for deficiancies.
Charger--univolt and anchor are synonymous, many good multi stage chargers out there. Save the fuse board and reuse it. Get rid of the excess iron (univolt).
Water heater---also the original, I am not real thrilled with the Suburban I have. To do it over I would get an on demand heater.
Parts for rebuilding a gaucho. New coverings on the Gaucho and new curtains.
New power vents (use less juice.
New lights, primarily flourescent, some LED and some original 1141's.
New Plumbing--all pex now
New black water tank....valve seat area was cracked.
Repaired most of the tambour doors one winter....great threads on that
New door and window seals.
Added a rock shield and a new awning.
New LED exterior running and brake lights
Rewired the break away and the 7 pin receptor.
Added a stereo (just an old car AM/FM-tap-cd player.
Fire place (My option as the furnace was only 19000 btu's)
Added second battery
Painted wheels & got baby moons
New Propane regulator (I need to replace that one as I do not like the auto change over feature)
One of the curved front windows (I had "help" in achieving the need for that project)
new signal booster antenna for TV
CB + antenna
New toilet---related to blackwater tank
3 15 gallon blue boys
Extra 30 amp cable
Permanent installed surge-guard, phase guard, voltage guard device.
New AC (I was PO'd--it was only 40 odd years old---how can they build that junk!----replace with high efficiency unit
4 tire covers
A few tubes of vulchem, parabond, and acry-r
A few things I forgot.
But--I turned on the tunes and did a project --usually two at a time, one inside and one outside depending on time of day and temp. I suffered through many miles of wandering down the back roads on my motorcycle to get to the AS so I could do a Saturday project.
It has been an incredible hobby
I am laid up for a few months but next spring--200 watts of solar.
