Our MH has not been used since covid.
last service was 2016. 2019 changed oil and filter and some injection cleaner.
Do any fluids etc do any harm if left too long?
e.g. does brake fluid corrode anything?

thanks all

You should have the fluids changed, and have a qualified chassis mechanic check bumper to bumper. 2016 is 7 years ago and 2019 is 4. How old are your tires? You need to have them inspected if not replaced as soon as possible. Probably need to have the roof inspected and resealed.

The answer is it depends and on far too many things for me to list.

OIL for example Blow by on the piston rings can cause the oil to turn acidic over many miles.. Now oil has acid neutralizers in it so this does not eat a hole in your oil pan...> But if you drove far enough .. Well I've actually seen it happen one time on a car.

Brake fluid (some of them) can absorb moisture out of the air then the brakes fail I've never seen that myself.. but i've read about it.

Oil can become tainted from use where it will etch main rod bearings. Reason for the six month or x miles in the owners manual.

Brake fluid absorbs moisture, so it needs to be changed periodically.

Antifreeze and ATF have a long self life, but also requires change per your owners manual

wouldn't hurt to have a qualified service tech go ofer everything now, changing the fluids that need to be changed, etc. If there is damage it can be corrected now before you leave on a trip next year. Wait till then to have rhe coach examined and you may find your trip is canceled.

The only problems I've had from old fluids is antifreeze going bad and eating holes in a radiator. It was 15+ years old.

"But was any harm done?"

Perhaps none other than normal component aging for stored vehicles. But in a sense irrelevant in that other than a thorough mechanic's inspection, all you can do is replace the fluids and then monitor for noise, leaks and performance issues. Otherwise whatever happens, happens. LACK of fluids, which have preserving/protective qualities for metals, plastics and especially elastomer rubbers, is an issue. But you simply have old fluids, although they haven't circulated through the various systems in a long time. If no issues arise afterwards, then don't sweat the storage time (although take steps to not repeat it). Replace all affected fluids per your owner's manual service schedule, replace belts and hoses if inspection reveals issues (personally I'd preventively replace them -- it would kill me to have a belt fail in a remote area knowing I could have installed a new $25 belt months earlier), and thoroughly inspect your tires including the inner sidewalls, your spare as well. Check the engine battery as well, preferably by pressing one's tongue against the terminals (recommended by my neighbor's German Shepherd), but there may be other methods as well.

No nothing is likely harmed.
I’d lol at the “next year” comment, but it’s been this long so , I suppose who cares at this point. If it’s been basically sitting unused for however many years and this is the first time you’re thinking about servicing it, it is what it is relatively speaking.
Personally sounds like the only thing you need to buy for it are a couple for sale signs , but that’s just me.
