We're shopping insurance ( RV America, USAA, State farm)
State Farm does not offer fulltimers insurance, which you'll need once you no longer have a house and homeowners insurance. Also check with places like Miller's RV Insurance, Gilbert's RV Insurance, Poliseek, etc. These are all insurance brokers who work with many insurance companies and specialize in RV and fulltimers insurance.
the two most mentioned seem to be Good Sams and Escapees. Perhaps pretty much the same but does anyone have an experiencd opinion?
There is no comparison between Good Sam and Escapees! While we are lifetime members of both, our lifetime membership in Good Sam was bought many years ago...if we had it to do all over again NOW, we would not belong to Good Sam. Of course, YMMV.
If you have not already done so, I highly recommend joining Escapees...which you'll have to do, anyway, if you want to use their mail forwarding service. IMO, it's a club (more like a family) that ALL fulltimers and serious RVers should belong to.
We currently live in San Antonio, Tx. As far as mail forwarding goes is the best option just to use, is it Escapees that's in Livingston, Tx, or SKP, or any other ideas?
Escapees and SKP are one and the same (say S...K...P out loud). Certainly, if Texas works out best for you as far as a domicile state, you can't find a mail forwarding service any better than that provided by the Escapees.
