I went with my friend to do his PDI on a new Coachman Cross Country he bought.
The same thing happened to us trying to get it in his driveway coming home from the dealer of all things.
The hitch dug into asphalt and stuck. The drive wheel was spinning an inch off the ground. Of course by this time all the neighbors are out giving advice, asking why he bought something so huge (39 ft.) etc.
We tried jacking it up but it would not budge.
The final solution after 2 hours of trying everything else was to manually lower the left rear stabilizing jack to raise the drive wheel. Then I was able to use a sledge hammer and drive a 2x12 block under the drive wheel. He backed off with no problem and the jack was ok. He later had his driveway regraded and all is well now.
By the way we did hook up a 4x4 GMC 2500 Sierra to the MH with a tow strap and try to pull it backwards. Would not budge.
