MS 2018 Montana

The MaxxAir fan in the bathroom is not behaving as it should! The fan comes on but the lid will not...it tries to but fails to open. Has any one of you have had this problem and what was the solution. Thank you for your help...!

Good day everyone!
Our 2018 3000RE Legacy Edition has a bad leak under the fan/microwave every time it rains. The water seaps behind the back board behind the stove and leaves a large puddle on the sink! I took out the outsider fan vent and resealled it (it was badly installed...) but that was not the problem...still leaks when it rains. Made a video of this and sent it to my dealer...got nothing back from them...not surprised! Where can this water come from? I checked the roof, the extension...everything seams to be in order. Has anyone of you had this problem and if yes, what was your solution? Thank you for your help.

Hi everyone!
We have a 2018 3000RE Legacy package. After owning this Montana for just over a year, 12,000 miles later, we have two flattened out axles with two worn out tires (two inches on the inside of the back tires). We took it in to an expert axle replacement shop and they brought the axles back and replaced the bad tires. They told us that this was a temporary solution. for about 2500 miles. They said that what we really needed was "double-up" or reinforced axles. Have any one of you ever heard about double-up or reinforced axles? Will this solve my problem? I have already spent more than $1700. and don't want to go thru this again. Can anyone reccomend a good axle replacement shop near northern tampa, more specifically, Hudson, Florida? Thank you for all your suggestions and help!
