Trust me the new trailer manuals are worse!
I have owned a wide variety of RV's over the years, the overall quality has gone down, and the manuals have become more about CYA legalese and less about how things actually work. One of the best manuals I had was on my 1975 Airstream, the owner's manual along with an additional service manual were outstanding. There were a few mis-prints and odd things, but they were very complete. I also had a 1970's Eldorado? pickup camper that came with a binder for the manual and was very complete. The only recently built things I have seen with decent manuals have been some higher end things like the Born Free coaches and some bus based ones. The regular stuff it all generic. Part of the problem being that they switch stuff up constantly and no two units appear to be built exactly the same.
