My bumper and winch question

Hey folks, I've had a (likely dumb) question about aftermarket bumpers and then I'm looking for opinions on two different ones.
My dumb question is..... installation of a winch onto a bumper. Do I need to remove these aftermarket bumpers to install the winches onto them then get them rewelded back on after? I'm just about ready to order a bumper but I don't and won't have a winch for at least a couple of months.

These are the two bumpers I'm looking at..ones a low profile and one is a full sized. I'm leaning towards the low profile. Has anyone gotten one similiar and regretted not going with a full sized one?

 

Yes you will need to take the bumper off to mount the winch onto it.

No, you will not weld the bumper on, it bolts on and off. It is act not the hard.

 

Oh, I thought they were all welded on. Perfect, thanks.
