Trak, Sway or Stabilizer ?

I have noticed a somewhat common error amongst RVers on forums. They read about problems and items that have been purchased to resolve those problems. Because of that the newby starts thinking they also need to buy items to fix an issue that hasn't even been discovered yet.

My suggestion is to take the new to you RV and go camping. For now, keep your money in your pocket. You may find shortcomings in your RV and you might not. Deal with whatever issues you have when you discover them. Don't spend money now exorcising issues you may not even have.
