I guess you have thought this out ok... I know this is a very convenient place to mount your generators but that sure would put your high dollar generators out in plain view and prone to thief.

I know I would worry myself sick everytime I had to leave the trailer unattended. Too big of a thief risk for me...
I only carry one 2KW Honda Generator and it is stowed securly to the tail gate corner of my truck bed. I also have a heavy plastic folding bed cover which lock. This keeps my generator out of sight until I have to use it. When I need to use it I just pull it out onto the truck tailgate and plug my trailer shore power cable into it.
My high dollar 2KW Honda EU2000i generator goes where I go...
