Whats the last thing you bought for your bay just because you wanted it and not because it needed it? I think the last thing i bought were some Hibiscus flower stickers back in 2007. She doesn't get much spent on her these days.
Timing light with rev counter. Dehumidifier. New oil pressure switch because someone on here explained how to check if the other one was broken, which it was. (After I bought a new bulb in the dash which wasn't)
back axle...engine before that ,probably the most I have spent so far ... Looking underneath, I have a big list....
A load of those little strong magnets so Mother can sew them into the hem of the new curtains I haven't told her she's making yet!
colour matching camping pots! btw. replacement mechanical parts of the bus shouldn't qualify as "things you don't need"
