Won't these slip off of the frame when walking in the trailer?

I have used them two times and no problem of them slipping off. They did help some in stabilizing the trailer, but not as much as I had hoped.

Puede servir para reforzar un motor home

Si, son perfecto para eso, sobre todo si vives cerca de la costa o el mar, ya que son resistentes al dejaste por el salitre.

Are these jacks able to lift a house to do repairs on a collapsed foundation?

Absolutely not, these stabilizer jacks are just that. They can not support that kind of weight. These are made to just keep your trailer or rv from tilting or rocking while parked.... made of aluminum ....

Will these work to lift a bed off a truck?

If the have a lift capacity of 6 thousand lbs, well then they should, like anything else, try at your own risk!
