I'm not too far away from you.
Do you guys ever go out to Cuddeback to sail? It's about eight miles off 395, so a little bit of a drive from the highway, but it's a great spot.
As far as good places to shop in So Cal, that's a tough one. We really had a hard time finding what we wanted here. We bought both of our toy haulers from Giant RV and we absolutely can't stand them.
You're going to need to do something custom for yours, so you'll really need to find a dealer to partner with you. I wonder if your best bet might be to shop through
The Complete List of Toy Haulers and find a floor plan you like, and then reach out to the factory and see if they can work with you.
I think there are more dealers in the central valley. I always see them when we drive up the 99. Maybe you can take a trip up the valley to shop.
