Vengeance 320a Generator

[gulftest52]

I have a 2018 Vengeance 320a toy hauler which is “generator ready.” I want to install a Cummins/Onan QG 5500 but there are MANY different iterations. I have all the stuff installed for the EVAP model and assume that’s the way to go. The EFI would require a fuel pump installation and more fuel feed and return lines than are currently already available from the installed fuel tank. There are also a lot of circuit breaker configurations including 30 and 20 amp and HACR CB’s, etc.

So.. The question is: What specific model is installed in the 320a’s and what type of circuit breakers are used?

I have two 15,000 BTU Dometic A/C’s to power.

Thanks for any info.

Continued research seems to show the QG 5500 EVAP HGJAB-7103 with (2) 30 amp and (1) 20 amp HACR.
