Front wheels of ground after using auto-jacks

Talked to the Service Advisor from Winnebago. Summary of the conversation is that they do not recommend letting the front tires hang off the ground. With lots of caveats, we'll need to perform a few steps to 'manually' get the wheels on to blocks, then manually lower the jacks for additional support. His position was from manufacturing warranty and insurance reasons. He said two things basically, 1) use auto-jacks for small level adjustments and 2) move to another site where the wheels do not come off the ground during leveling. Guess we were naive in believing wheels off the ground was okay - during pick-up orientation the front wheels were off the ground :-)

Thanks for all the advice.
