It seems logical to turn your truck wheels in the opposite direction of where you want to turn, then back up and straighten so your fifth wheel can go straight in.

That's because your RV wheels are still turned. Those wheels are not pointed straight like your truck’s.
Unfortunately, that's not how a fifth wheel moves.
Place your hands at the bottom of the steering wheel, thumbs pointed out. Then turn in the same direction want the rig to go.
A partner is helpful when you're backing up a fifth wheel.
This requires plenty of space. Pull all the way forward so all your tires are aligned straight. Then gradually back in without turning your truck tires..
Having a partner stand at the back left corner of your target.
Pull past the parking spot. Then turn your truck wheels to the right.
Back up until your truck is at a wide ‘v’ to the RV.
Turn steering wheel to the left of your target). Then back in.
Ask your partner: are you going in the right direction?
Correct and straighten out your RV tires. Then back up.

You will back up into your blind spot to get into your campsite.
See the Backing In Left instructions. Do them in an opposite manner.
A partner is critical for this one.
Ask your partner to use the same hand movements and directional words every time you back up.
