Thinking about a new generator

I’ve got a big contractor style generator that I’m thinking about replacing with something smaller and quiet. I only need to use it a couple of times during deer season so I won’t need it to run an AC unit. Just lights, tv and heater blower. I’m thinking of getting one of the 2000 watt champion generators and using a 30 amp to 15 adaptor. Will I mess anything up by using the adaptor? My other option is to add a parallel kit that has the 30 amp rv outlet. Can I run a parallel kit without having it hooked to 2 generators just to get access to a 30 amp plug?
