I have some significant rust spots on my camper legs. Anybody have any suggestions to get it off before I repaint it?

Right now I’m using a Milwaukee hand drill with wire brushes… and it seems way underpowered….it’s taking too long and I’m struggling to get to the unrusted bear metal…..

I’m positive I’m missing the obvious, so let me know what you think!

I’d like to remove the 4 legs to do a little work on them …..

Can anyone suggest a way to support the weight of the camper while doing so?

Thanks already!

Both my airbags are leaking from what appears to be the actual nipple where you push the air hose in to fill it.

Is there a way to simply replace the end nipple piece instead of having to get crazy and tear lots of things apart?

Thanks already!!!!
