All things compared, I'd say they are probably close to equal. Items on RVs are not as high quality, and tend to break more often. Items on boats are higher quality, so they cost a lot more to repair.
After doing a huge investigation into RVing full time vs. sailing, we are proud to say we are sticking with sailing!!
It's the parking each night thing that really cinched it for us. It's hard to find good spots that you could stay at for a couple days to a week at a time without paying.
When we looked at all the considerations, I decided to work
from the boat
and keep our boat, which I had very recently looked at selling because it costs so much. Turns out, we find it worthwhile to work
extra hard for a couple years to pay it off. (Thread drift alert!)
I'd say they're a tie though. What money
you have, you will spend.
