My Bertha was one of the first ones made and it was a bear to put togather. It had a few flaws but I have had it for years now and it works fine. No problem with the bolts though. I never use the lift so don't know if it works or not.
One thing I do not like about it is the sides only fold over the top not down the sides so it is open all the time. It is 7 ft long. Had to have it cause my machine is larger than regular machines and wouldn't fit in a regular cabinet.
So true about groceries but a good laugh anyway.
