GFog,
Your post was buried in a mega thread, so I moved it to its own thread.
We bought just outside Dallas too (back in the ol' days), just not MHSRV. The trip can be interstate all the way...but hope you take a moment or two to see some sights
35W out of Alvarado, to I-20, to the 10, to the 210 around LA, then north on the 5 is pretty easy.
Best Luck
