The Keystone Raptor and Fusion both come with gas Onan 5500s with 30 gallon fuel tanks. Not sure how similar they are to a Montana but might give you an idea of how Keystone lays out a gas genny on their fifth wheels if you wanted to go that direction.
I have a built-in gas Onan 5500 on my toy hauler with push button start and it works well for the situations you describe. Only issue is I am on my 3rd carb. I do use Stabil and still get issues (genny shutting down under load, won't start, surging, various codes, etc.). Search "Onan problems" on here and you'll get lots of hits and most of these problems are with gas models and can be remedied with a carb swap. The carb is actually very easy to change out in about 15 minutes at a cost of around $300 (Amazon). I installed a fuel line shutoff after my most recent carb swap and run the carb dry for storage so hopefully that will help.
