Welcome to iRV2. I'm not sure why you feel a push. Coaches all have quite a bit of overhang behind the rear axle. My coach has more overhang than your coach. Assuming all the suspension is in good working order and everything is tight, look to see if you have a trac bar installed in the rear axle. If not, consider this after market device. First check to see that the rear chassis/suspension is okay.
