Default Generator won't power my AC unit

I have a 93 Gulfstream Innsbruck that I fixed up for a hunting camp. It has a Coleman Mach 13,500 BTU roof unit which I assume is original equipment. This week I tried running it on low with my 3500 Watt inverter generator. It kept shutting the generator down.
I also have a 2015 model Crossroads travel trailer which has a Coleman Mach 3 AC 13,500 BTU unit. I used it all last summer with the AC on high on generator power with no problems. If I ran the AC on low the generator would even run in eco mode at lower RPMs.
What could be the big difference here? The Gulfstream's AC ran fine on shore power when I checked it.
