I am going to install a replacement french door unit in my family room. The new unit requires a 72″ wide rough opening. After removing the inside trim, I found that the existing rough opening is only 70 1/4″ wide. In order to gain the additonal width, I thought about replacing the trimmer studs with new ones that have been cut down to 1″ thick, then glueing and screwing the new trimmers to the existing full height studs. The house is a two story, and the french door opening is on the first first, so the header is load bearing. Is this ok? Thanks,

Jukey,
Might get slaughtered for opening my big trap, but... are you sure the wall is load bearing? Just because it is on the first floor doesn't make it necessarily load bearing. If it isn't you can probably get away with your 1" trimmers. If it is load bearing, I would replace the header and reframe. You aren't talking about a huge area, just a little bit of blue board and mud and you are back where you started. And you'll sleep better.
French doors can be finicky in properly framed RO's. Let you header sag even a little bit cuz of undersized trimmers and that door will give you problems forever. If you are the least bit unsure (reasonable doubt!) about this wall's function, by all means go with the reframe. 1" trimmers may work....but it's a gamble IMHO.
If you take the old trimmers out and cut them down to 1" you'll only gain 1", so that would give you a R.O of 71-1/4". That's probably what the door measures. Hiow are you going to get it in. What's above this header?

Do you have the new unit on site? If so, measure it and see if you really need the full 72". If you don't need to lose too much width, might it be easier to shorten the head jamb and re-work the astragal? It's a judgement call as to how much asymmetry is acceptable.

Is the opening in a gable end? Or does the roof overhang the second story above?
if it is a gable end, then you MIGHT be able to "get away" with one. But if not, then take a deep breath and do it right.
It's likely that your old opening isn't square, so your new rough opening will be undersized if you try to cheat the manufacturers RO, and the door won't fit. Double check the diagonals!
If it were me, I would, without question, make a longer header sandwich of a couple 2 x 10s and 1/2 ply and turn your full studs into trimmers , and add the proper new elements.
Look at it this way, if you were going to a smaller opening, you'd have to figure out how to extend the siding, which is potentially a much bigger headache!

Wow! I love this forum. See, I missed that. I was assuming this door was an interior French Door. You picked up on him saying something about the interior trim (as opposed to exterior)....good catch. And before that, Joe noticed the RO numbers didn't match up.
