Exterior Trim Repair (for a noob)

Well I'm very new to Rving and yesterday while I was pulling out of a spot there was a bit more of a decline than I should have been on and the front of my fifth wheel came in contact with the truck. Thankfully it was fairly minor as far as I can tell but a piece of the trim (moulding?) was bent out and the wood on the bottom popped out of place.

Can anyone give me some tips on how to fix it? Explaining it like you would to a five year old would be great, lol. I assume I'll have to pull the side piece off to where it's bent and bend it back and pull the bottom piece off to the same place and get that wood back under it. Then reattach both with some glue (4200?) and put sealant around it again. How would I go about clamping it together to dry?

We are currently in the middle of a long trip, we'll be traveling heavily for the next several weeks. I assume we'd have to give it at least a day or two to dry right? I was thinking maybe we could just to a temporary fix until we get where we are going. I have some Alex plus and was just thinking of shooting some of that where it is bent to keep any water from getting down there or even just covering it with a bit of duck tape.

There are a few pictures below so you can see what I'm talking about. Thanks for the help!
