Welcome and congrats! You will learn a great deal from the experienced people in this forum! We purchased our first RV a few months ago. If you can get the vin# for your chassis you can follow this link and get the specs for your specific RV chassis.

Our Vegas is on an E450 chassis and it came with factory installed front and rear anti-sway/roll bars. It also came with factory installed HD shocks. When we test drove it there was a lot of play in the steering wheel. We also got shoved all around by wind and 18 wheelers on our way home with our new purchase. With all of the traffic and construction on I-10 my husband was exhausted by the time we got home. We had an alignment done after loading it and we added a steering stabilizer and a rear trac bar. The handling has greatly improved. Good luck!
