Enough of the whatabouts & the what ifs. If you have something that wears out & is hard to find, get a spare when you can & carry it.
Rim, tire, brake pads, oil filter, fuel filter, doesn't matter. Sitting by the side of the road without it does you no good. At least having the part only leaves the problem of replacing it.
We are off to Alaska again in 2023. We will be starting off with new rubber all round. We will also be carrying a spare brake drum with Nev R Lube bearings mounted, spare truck brake pads, serpentine belt, oil filter, primary & secondary fuel filter, spare trailer wet bolts, landing leg parts, slide gears, two spare tires (truck & trailer use same tire), numerous other bits & pieces collected over the years, very few of them stock items in an auto store.
We even carry a spare trailer axle!
We are former cruising boaters where there is NO roadside assistance. We carried all of our spares, even used stuff that had some life left in it, & knew how to install it.
The trailer broke a spring in Newfoundland this year. Lucky. We were able to get a replacement pair, slightly different, & changed out both sides ourselves. Still have the remaining one good spring pack just in case.
With all of the stuff that goes wrong with these RVs I don't know how some helpless people get by.
