I bottomed out and bent a pin so I completely understand your issue. After doing a bunch of research I found out that the levelers on my 29MV should have been 7-9" off the ground. Mine was not even 6".
I sent an email to the mother ship (Jayco customer service) and they authorized to have the pin replaced as well as have all the jacks raised up to their proper height
