MotorHome and Towing World provide great lists of which vehicles can be towed and which can't.
Check the lists, then CHECK THE OWNER'S MANUAL!
The links below aren't strictly RV-related, but contain some information that I thought might be of interest. The People's Guide contains alot of great info all about RV travel, retiring, etc. in Mexico. The AVG site has a free download of virus software, in case you don't yet have some on your computer. The Snopes site is a great source for determining if what you're heard is true or a scam -- i.e., email alerts, etc. Wikipedia and Merriam-Webster (dictionary/thesaurus) are just two great sources that I use a lot.
