I'm brand new to the forum and have been enjoying the RV lifestyle for a couple of years now, but with the exception of the occasional bride or hill I have no steep grade towing experience. My rig is a 28ft travel trailer towed by a Chevy 1 ton diesel, and I'm planning a trip from Tx to Oregon via I10 West and then I-5 North. I've read in the Destinations topic of the forum that the "grapevine" is pretty bad (I5 N of Six Flags in CA). If anyone can provide any tips or advice I'd be very grateful. Thanks. I've only been a member 30 minutes and I've already learned alot.
