By roll bar do you mean the headache type roll bar?
Also, are you set on a roll bar? You can get a high quality front bumper that has a winch mount in it. C4x4 makes some REALLY good ones. A couple members have them on here. Here's a linkC4x4
FYI, I am not associated with them at all.
If you are going to be running aux lights and a winch you're going to want to upgrade your alternator.
Nobody is going to make a tonneau cover that will handle a roll bar if it is the type I are thinking about. You are going to have to do something custom.
