Microwave wobble

[Gubs]

Just returned from a 3,000 mile trip and noticed the microwave seems to be loose and it wobbles a bit when my wife pushes on the bottom of the unit. Didn't notice this before! Tried to tighten the bolts on the top but they seem tight. Has anyone else experienced this problem or is it just the way it is and we are just now noticing it?
If this is a problem how do you tighten the bolts on the top of the microwave. We have 2020 Montana 3121RL and it's difficult to reach the bolts because of the "useless" wine rack on the top of the microwave!!
Any assistance is welcome!!! Thanks in advance.

We replaced our HighPointe microwave when it failed.
The microwave sits in a bracket at the back then the bolts are installed down from the top.
You will need to remove the microwave and check the bracket at the back to be sure it is fully engaged.
I used leveling blocks on the cooktop to support its weight going in and out.

When I had to replace mine I used a jack to support the unit. Took all the weight off the bolts and they were easy to turn with a short screwdriver,
