Is my "boost assist" connected correctly?
I've been puling my batteries at the end of the season and occasionally charge them throughout the winter in my garage. But I want to make sure I have that starting boost cable attached the right way....

Boost would go to positive assuming there's only one boost cable (which would be typical). The negative return is through the shared chassis ground.
Whichever other wire is connected to chassis ground goes to negative. Whichever other wire is not connected to chassis ground but to fuses etc. goes to positive.
Relying on length as a general rule is rather unwise; I don't think there's any defined consistency there. If you know it's correct for your particular RV, that's of course a different matter entirely. (For that matter, relying on colors being correct can be problematic as well; a battery cable may have been replaced, and the correct color may not have been handy when it was replaced.)
