Welcome to the group and to the world of FGRV's
Gotta mention that you are setting up a couple of opposing criteria, budget and condition that may reduce the number of 13'er's available to you.
Right now is peak buying season for these birds and finding a decent one in that price range in California is going to be a tough one.
Keep in mind that "After Purchase" expenses usually have to be anticipated, ranging from new tires
to, in the case of many older Scamp
types, a new torsion axle
. The good news it that it sounds like you are open to buying a "fixer" and that will make it easier to find, but "safe towing ready" may take some initial investment.
I suggest that you follow the many ads on <<<fiberglass-rv-4sale.com>>> and also click on the "Other makes" menu for less common names and alternatives. Right now there are a couple of Hunter Compacts listed in your price range. (If you see the one in Clear Lake relisted, it has significant problems and was way overpriced when the ad was taken down recently)
Good luck and good hunting
BTW: where in CA are you located????
