1. If you have Carlisle Tires, replace them right away! We had a blowout our second trip out with our Rage'n and it did some damage! On the plus side, Carlisle paid for all the damages and replaced all our tires. We sold the new tires and bought Goodyear Marathons and have been happy ever since.
2. Definately get a built in generator if you can, and get a 4K or larger if you want to run your a/c.
3. You can never have enough battery power. Conserve power as much as possible or you will have dead batteries and no furnace in the morning.
4. Driving fast over railroad tracks will break leaf springs.
5. Lock up all your toys. Theives are everywhere.
6. Bring extra drinking water and food just in case you break down and are stuck out in the middle of nowhere!
7. Make sure you are within the weight carrying capacity of your trailer. Weigh your rig at a truck stop to be sure.
