TJ Door frames - stupid newbie question

Hey guys,

Got my first TJ about a month ago... 2004 model, soft top with half
doors. Of course, since then we've had the second rainiest June on
record here in Central Florida, and July ain't looking much better
(grumble grumble). So we've just been taking the top down on the
weekend, putting it back up Sunday night since I need to drive it to
work and it rains every day around 4PM.

I got a Clover Patch for the rear & side windows, and I've been putting
the door frames under it (strapped down just in case). I wanted to have
as much as possible with me in case an unexpected shower came up.

So yesterday my wife asked, "Why do we take the door frames off?
They're the last thing we take off, and the first thing to go back
on..." I couldn't think of a good answer, other than "That's what the
video says to do." We took the top down this morning and left them on,
and I don't see any difference. Is it just a "looks" thing? I'm just
thinking if there is a sudden storm, that's one less step (or two if
you're alone).

Is there any problem with leaving them on with the top down?

thanks,

Garg
