As Roger mentioned, and as in Drew's example, the current selling price can be similar to the original new price
; in my case, I met some people at a campsite who considered buying a 17' Boler
like mine new in 1980, for about the price that they are routinely offered now. Mine needed some TLC, so I got it for significantly less (about half).
One problem with this comparison is that a dollar was worth a lot more decades ago than it is now, due to inflation
. Buying a trailer for a few thousand dollars and selling it in five years for the same number of dollars isn't free: your money will be worth less at the end of that time (the inflation loss), and
you've borrowed that money (and paid interest) or used some savings (and thus passed up investment income) so you will have paid for the time-value of the money
. Is losing that value and tying up the cost of the trailer, in addition to maintenance cost, worthwhile? Likely yes, if
you use it enough.
Since the fiberglass shells of our trailers generally survive well, the trailers hold their value better than conventional "stick built" designs
; they're sort of like the aluminum shell trailers (Airstream, etc) in that respect, for the same reason.
