I did find a generic pull trailer manual on the Winnebego site:
https://winnebagoind.com/resources/manuals/operatormanuals2011.php
This manual seems to cover most of what has been said regarding advice so far.
To be clear, I will want to raise the tires off the ground to remove the wheels. The manual I referred to doesn't cover this. How do you remove all four wheels at once (technique)?
Use of the jack stands? Is this to augment the the stabilizing jacks? And I looked up the Trailer Aid term and found that it is in line with the recommendation of the online manual telling you to drive up on 2x6s. What is the purpose of driving up on the Trailer Aid (or 2x6s)?
Anyway, a quick how to on how to safely get all four tires off would be appreciated. I only looked at the trailer briefly yesterday but there is a hand crank jack part of the tounge and I think there was a scissors jack in the storage area and crank. There are stabilizer jacks on the trailer as well.
