As mentioned by one responder, lowering the front wheels tire pressure may prevent a tendency to oversteer and help with stability. At least, that is what I do. The recommended tire pressures for our Pleasureway Plateau TS are 55 front and 80 rear, clearly a way to obviate oversteer. I tried a higher pressure up front and the RV seemed to be more prone to side to side oversteer. As it is now, it is great and no problem. Rear airbags are a big help too as are wheel spacers on some B models, especially those with Ford chassis.
