You made a good choice in the Argosy. I have a 78 24ft Argosy. I also showed Standard Poodles for about 25 years and traveled in a 22ft
Caravel. Loved every minute of it. Try parking next to someone you know who's driving a big diesel rig with a generator. Always worked for me. I did have a Honda generator too, but a lot of the time I found ways to plug in on the show sites. Those overhead and over sink lights are your
12v. The outlets are 110 when you're plugged in to shore power. I don't use my central heater either, but I do have the catalytic heater on the wall. It uses no
12v power, actually no electric at all, and will keep you pretty warm. Down here in Oklahoma, we mostly worry about using AC due to the heat. Suffered through some pretty rough heat and rain at the shows. We don't have outdoor shows as a rule any longer, just not a fun thing to do around here. Good luck with your Argosy. You made a good choice.
