Oil
I’m not really mechanically inclined but I can do simple stuff. So yesterday I changed the oil in my 2000 F350 7.3l diesel. Apparently I over filled by about (guessing) a quart. I’m about to drive the beast from FL to AK. Should I take out the over fill, or will it be okay to leave it like it is?
TIA for your help. This forum is where I turn to regularly. It has been an invaluable source of support and information.
THANKS EVERYONE. I DRAINED OUT THE EXCESS. GOOD TO GO!

I am not sure how much leeway a 7.3 has, but it's typically a good idea to drain what you need to so it is not overfilled otherwise the excess oil will find a way out of the engine.
The 6.7 PSD for example you can overfill the earlier models by a couple quarts 15 instead of 13 quarts and they can handle that. In fact the newer models just changed the dipstick itself and are listed as 15qt capacity versus the 13qt on my older '11 model. Nothing changed internally to increase capacity.
On my Harley 103 Twin Cam, if I overfill it, the oil gets blown out into the air cleaner, which often gets oil in it even if I don't overfill if I let the engine get too hot.
My older 351M in my '79, if I overfill it will find the path of least resistance to get rid of the excess oil, that could be PCV or air breather, front or rear seals on the crank, or any other potential spot that could leak.

If you just like really don't want to crawl back under truck and try to only drain out a little oil, while not making a huge mess in the process, you could go down to your local tractor supply, get a cattle dosing syringe and some plastic tubing, then just suck the excess oil out the dipstick tube.
You could even keep the excess oil in a bottle and re-add it back in later as needed if you really wanted to.
Looks like a four pack of cattle syringes is $6.

Mine leaks enough that over-full is a very temporary problem. How far over the the full line is it? I frequently keep mine within an 1/8" either under or over the full line. More than that I would feel uncomfortable and drain some out.
BTW - that is an extreme road trip! Good luck and have fun!

Or one of these which would be easier. https://www.harborfreight.com/multi-...ump-63144.html
I use the syringe method to draw oil samples to send off for used oil analysis. The tube that connects to a livestock syringe is small enough to fit down the dipstick tube.

That said, I don't think a quart in a 7.3 is going to hurt anything - when it's running it won't be over full anymore.

Look up marine/boat oil extractors. They're built specifically for this, especially for I/Os where you can't drain the oil out the bottom of the pan. I used to have one but I got rid of my I/O.

I try to stay away from anything boat or marine related because of the boat/ marine tax. Just like the "overland" tax, anything that says its for boat/ marine use on it is instantly quadruple the price it otherwise would be. And since OP will likely only need / use this exactly one time, I figured $6 worth of livestock syringes is worth the trouble and not making a huge mess .
Quick google search says the cheapest boat oil extractor on Amazon, made by Vevor which is cheap stuff, goes for $43.99 (heck the Harbor Freight one is $84.99), hate to see what the actual name brand/ non-knockoffs ones cost. So for a one-time use type thing, I'll stick with the $6 option from tractor supply.
