We have a 2018 25BH, took it out last weekend for the first time. Sorry to hear you are having so many problems. I have not noticed anything obvious so far. I added a 4" memory foam topper to the bed and it's pretty comfortable. I work midnight shift and many weekends so the wife complained about not being able to clean house while I'm sleeping. I found I could sleep fairly well in the RV after putting blackout material in the windows.
This is only my 2nd trip in an RV and it poured down rain most of the weekend so we were stuck inside most of the time. Maybe a rookie mistake but the wife wanted the awning out so we could get out the door without getting soaked. I set the pins to max tilt but water still pooled on the awning. I hit the button to bring it back in and the one side collapsed. After I got all the rain off of it I got the arm to go back in place but now when I extend the awning to near full open, it keeps going out instead of stopping. It stops just before I'm afraid of it going too far, I was told not to go past a certain point. I keep it set up with the bump out extended in my driveway for use as a man cave and haven't noticed any problems so far. I still need to check underneath to look for any issues. I have a 2013 F-150 5.0 and it really has to downshift going uphill. Otherwise, haven't had an issue towing it.
One issue I have is backing it into the driveway. There is no way around it, I have to drive into the yard to back it in and that means tearing up the lawn. Because of that and the wife having no idea how to assist with helping to guide me back I bought a dolly to move it around.

When I tried to turn with it, one wheel comes off the ground and the whole thing nearly falls over. At least I was able to return it to Amazon with no restocking fee.
