I can not offer any meaningful advice about your trip, but if you post information about your equipment you will save a lot of time and get more meaningful answers up front. Since you are in crunchville time wise, that will help a lot.
Post information about your tow vehicle such as make, model (year), engine, basically everything that you can post, and you will get plenty of advice. People here are johnny on the spot when someone needs help / advice. It is a very good community.
Good luck, safe journey, and hope all goes well.
