Front wheels of ground after using auto-jacks

On our first shakedown cruise of our RV, we found that the front wheels of the coach were off the ground after using the auto-jacks.

We put a couple of nice jack pads under the front jacks to keep the jacks from being fully extended (suggested by RV service tech). We also put a couple of 12x12x2 PT redwood blocks under the front wheels.

After all that work, we noticed light or gaps between the hanging front wheels and blocks. RV Service Tech told me that was bad for the axles and the jacks. Trying to figure out how to solve this problem.

Should I use shims to wedge the tires front and back of wheels? or do something else. Seems strange to drive up on blocks when I have jacks, but I am new to Class A RVs, and perhaps naive. Moving the RV to a better spot is not always possible if the CG is full and due to a tree we could not fully use the 40' pad we were given (our coach is 31').

On our Winnebago Vista, we have a manual button for the jacks, but have not figured out how to use the manual button to raise/lower the coach. There is a auto-lower button but I assume that fully retracts all four jacks (have contacted Winnebago Tech Support given the manual was not helpful at all).

For those RV veterans out there, this might be a really naive posting but I really do not want to damage or coach or have a safety issue for my family.

Main thing is, that you don't raise the rear off the ground and lose your parking brake function.
We've had the front wheels off the ground, many a time, with two different coaches over the last 10yrs, without issue.
If you have some concern, you might want to just put some blocks under the jacks, so they won't extend so far and not worry about the wheels hanging on the suspension. Still fail to see the harm in that over short stays, if any.
To engage manual operation, you'll have to hold down on the button for a bit and until the light comes on. Then engage the front first and probably like the auto mode does, until they make contact with the ground and before shifting to the rear control. Once down and level front to rear, you can rock it to one side or the other.
We use manual on the front, to dump water off the slides on occasion. Then lower with the master (that's all there is), until it looks level from the outside, before pulling in the slides. Seems that the front is all that immediately retracts, when in manual like this and stops when released.
Some with manual who don't do things right, have popped the windshield on some coaches, but even with our old National and bouncing it all over, we never had such an occurrence.
