DH and I have been there, done that and we're only 5 months into a trailer so far.
Ripped a cabinet door off - check
Drove away without the levelers up - check
Broke the antenna - check
Lost plastic bowls and cups to breakage when cab doors flew open - check
Spilled sewage when we forgot to close the valve - check
Had the black tank come up to the rim of toilet - check
Smashed things in storage under seats in slide - check
Tweaked the bath door when putting in bed slide - check
Solution: I walk around the rig 2 times to check for things. I also got those tiny bungie cords and wrap them around two opposing cab doors to keep them shut. We no longer store anything small in slide storage. And I make sure all doors are closed inside before I close the 2 slides.
