Question here, Some advice or opinion requested.

MY Class A Motor Home, Fleetwood, Workhorse 8.1 P32 Chassis. I purchased it 3 years ago with 18000 miles on it. Have been using to for hide out on the weekends and doing maintainence during the pandemic; had planned on hitting the road for a couple years. Well, as you know, Covid delayed that. I know have 20000 miles on it.

It was maintained my prior owner. I have, due to age, gone ahead and replaced much, including brakes, autopark brake solenoids, V-Belts, Tires, fresh water pump, etc.

Due to age, what are your thoughts about the engine water pump and thermostat being replaced now, before I go on the road?

Imho you want to flush and change coolant and new fail safe thermostat.. use lowest thermostat you are comfortable with.. just closely inspect engine water pump.. check fan and fan clutch.. inspect hoses.. and maybe change top hoses if they are hard to get at.. you don't mention the following... p/s oil, brake oil, I would add those.. and generator oil..
Closely inspect radiator between condenser and radiator.. don't be fooled by just looking at front of the condenser.. look between the two..
With rv sitting tat long.. you must think about critters... critters love to eat on rubber fuel lines and short wiring and nest in worst places... so when things go haywire and don't make sense then keep critters in the back of your mind all the time..
Ofcouse.. new eng and trans oil and filters.. new fuel filter..
Good luck and keep us posted

Oh.. sorry.. Change out auto park system oil.. it can get moisture in it and rust the guts inside.. if you are not having problems with auto park system.. see if po upgraded the a/p system switches.. if they did.. you are almost good to go.. if not.. Change them and keep old ones for spares.. do change the relay.. don't cheap out here... 50 to 70amp hi quality relay..
Just inspect brake pads and rotors.. but lube slide pins.. check brake lines and hoses.. replace any needed..
Good luck and keep us posted

Coolant flush and swap in a new T stat then roll.

And get a 'radiator genie' and flush from the back side. Move the lower shroud off the clips and slide it up from bottom.

Thank You All..
1) I flushed the cooling system, did not change the thermostat, will do this week.

2) I installed the upgraded autopark solenoids, Purchased the Upgrade kit from Workhorse, very easy to install, (did have trouble breaking loose the one solenoid underneath; read that everyone does).

3) I did check brake system and did change the brake pads due to the age of them. Flushed the brake hydraulic system complete.

4) I change the generator (4000) oil often and the spark plug. I changed the fuel filter and fuel pump, air filter also. I even added another filter in the fuel line after the fuel tank

5) New Wiper blades

6) I hated the size of the washer bottle, way too small and only one pump. I obtained one at pick n pull that fit, 3 liter and has two pumps, very nice now.

7) I flushed the fresh water tank a few times now; I do use a water filter inline when I get water for the tank. I also replaced the water pump, (kept the original as a spare.

8) New fan belts

9) new Alternator due to failure, (crazy, not that many miles on unit).

10) new Fan clutch, Just old I guess.

11) All New tires, obtained from a truck shop tire shop. Good Prices on good
12 ply tires, $ 1,100.00 installed. (no not cheap china made tires).

12) then there is general maintenance

13) oh yes I removed all the stripes and Painted my stripes on Red, Black,
Dark Gray. I am going to paint the lower Black. ( I used to own a body
shop for years before I retired.

14) Painted Roof with RV Roof Coating a couple times now. Just purchased
seam tape, EternaBond.
Going to tape the seams on the roof Sunday.

15) Ohhh Yes, Transmission, GM 4L80e. I installed an upgraded Pan, cooling
fins, adds 3 quarts, aluminum. specs say 7-8 quarts when servicing; with
new pan it took 11 quarts.

Fit very nice, all new bolts, washers, gasket
2 filters, Transmission was like new inside; absolutely clean, red not dirty
at all.

16) I tow my Honda CRV behind unit; I installed a tow set up on MH and
Honda.

17) I also did install cameras front and rear, recording. Can see car being
towed and have from camera to record all the jerks that cut motor
homes off just to get one car ahead, :(

18) New Stereo system

19) I had purchased and installed 2 years ago a tire pressure monitor with
sensors. Loving it, constant pressure readings now on the dash. This is
so great not worrying about a tire getting low while driving.

Again, thank you for your input and advice.
