Great you and your truck have made it safe! Just to be safe - are you sure the engine has not sucked any water? If the water goes over the hood and you don't have a snorkel installed it might be wise to check if there's no water in the engine oil. Few seconds of water splash shouldn't do you no harm at all but checking the oil and the air filter chamber doesn't cost a penny. Anyway, if water got in there you would probably noticed that - your engine would be gone... Don't get me wrong, I don't wanna sound scary, it's just some experience with doing submarine jobs with my jeeps that make me always a bit curious (I've manage to spoil a tranny in my Wrangler but we were sitting in the dashboard high water for a good 15 minutes and the tranny didn't have the air vents replaced high into the cab).
There's a narrow but busy street close to my house that has a serious problems with drainage - after any storm or hard rain only SOME SUVs and trucks can make it through a quite high water that stays there for hours. I remember slaloming on my 33"s around a number of stuck cars which sucked water in. Total mess!
Other thing is to turn off the lights before entering any high water - the difference in temperature can negatively effect the beams glass.
Overall - welcome to the club of those who say "what? my truck can't swim? just watch THIS!!!"
