[Jerr G] Don't know about Roadtrek,but I have driven 2ea class Bs and now have a Coach House( another class B equilent to Roadtrek) have driven a jillion miles or so with no stability problems. The secret is in the tires and tire pressure. Make sure tires are rated for the total load plus a safety margin and inflate to max pressure as on the tire. They build these coaches usually to max GVWR before you ever load you,your gear and fluids. This puts you overweight. The side wall S/B at least 8 ply.
