I ended up taking my truck to a different shop that a friend works at. I asked them to rebuild the carb. They found that the gasket was blown causing the gas to spit out the top of the carb. They went through everything else retuned it. They also replaced the spark plugs because they were too fouled that cleaning did not help. They also replaced the ignition coil as it was not working either. They believe that the moisture may have ruined it so they directly wired to it instead of using the original cap/plug. Last thing they found was the alternator belt was loose. They believe this was causing inconsistent charging or not charging at all which caused me to loose electrical power going down the road.
I drove my truck today and it started very well (24 degrees out today). However, I kept hearing popping sounds as I was accelerating. Around 20-40mph it happened the most about 4 times in my 30 minute drive. Happened once around 50mph. After 15 minutes it did not happen again. I am bringing my truck back to this shop tomorrow for them to look at it again.
Is there anything specific I should ask them about? Anything I should check to make sure they do before I get it back again?

I brought my truck back to these mechanics and told them about the backfiring and the unstable idling. I noticed a couple vacuum lines on the air cleaner that weren’t connected to anything so I asked them to fix that as well.
They said that those lines not being connected was causing a vacuum leak in the system which was causing the backfiring and unstable idling. They also retuned the carb again after connecting those.
This morning it is 9 degrees out and I was able to start my truck with relative ease. It was up to temperature in 6 minutes. No idling issues, no backfiring, and I made it to work without any problems.
Overall, it seems the issue was the gasket in the carb that was leaking causing flooding, fouling my spark plugs, moisture in the ignition coil which caused it to burn out, and the alternator belt being loose so the battery wasn’t properly charging. I feel fairly confident that it is drivable now.
Thank you again for all the help and advice. I have learned so much and appreciate the help of the community to get me back on the road.
