Wow nobody seems to agree on anything. Drove it back temp gauge never even got to operating temp no problems. Lower idler pulley locked up tight. Upper pulley starting to go so changed them both.
On another note AAA is a rip off at that price. I have towing added on to my auto insurance for only $22 a year
Perhaps the "engine never got up to temp" because without the water pump the cooling wasn't flowing.
Some towing packages have different rates depending on how far they will tow you.
I have a spare serpentine, idler, and tensioner in my toolbox. Easy fix if you have the parts, I go far from home and deep into the mountains.

I had to go 10mi in my OBS when the idler locked up and ate the belt.
I thought about towing it, then I thought... Oh well, if I cook the engine, all the more reason to dump the 5.0 for a 5.7. It did it no trouble at all (other than steering 32's when I was trying to park it in my buddies driveway).
I can say I would be hesitant to do the same with a Dmax, as if it did cook, it wouldn't be a day and $500 to swap for a low miles long block, as it would have been in my case.
It's generally not considered a good idea. I'm not 100% sure where the temp sensor that feeds the gauge but a good chance it would never read a high temperature because the coolant was not circulating. This allows concentrated hot spots throughout the engine.
Glad you made it okay and hopefully you didn't cause any longterm damage.
The water pump is gear driven, so other then no power steering or power brakes not really a problem.
Biggest problem is the battery power as you will have no alt.
I have done it to, when my idler went.
