Insurance and Texas RGV zip codes

(Sorry, this was also somehow posted to the Monaco owners forum whereas I meant for it to go here)
Not that it will make a WHOLE lot of difference where we choose to site our new (to us) fifth wheeler which now sits out of Texas at a dealer's lot ....ready to be hauled down when we find a park to put it. But in talking to prospective insurance companys it was a mandatory thing with them to KNOW where the rig would be sited ZIP code wise. The cost from ZIP to ZIP could be significant. For instance I asked for prospective quotes for Mission (78572) and got $838. Asked for quote for Alamo (78516) and got $932. So it was nearly $100 more just for a change in zips.
So, I will ask anyway....does anyone know any "more reasonable" zips in the RGV as far as insurance cost go? How about a ZIP to stay away from considering because even more costly than the two zips above?
