The red leg of the panel in my mobile home reads 240 volt from hot to neutral. What might be the cause of this? It's causing the light bulbs to pop, and I'm afraid to turn on any appliances

The output appears to be ungrounded or center grounded. It could be a transformer intended for outdoor tools in UK. If there is also a safety ground 3 wire plug, it could be coupling some of the harmonic current from the switch mode active power supply (which should be flowing equally on hot and neutral) on the safety ground. That would be unbalanced current and trip the GFCI. The smaller transformer could be wired with normal grounding or it may have a plastic case. Adding filtering to the mains input could fix the GFCI issue.
Based on your updated readings (120v between h1-h2, 120v between h2-neutral, and 240 between h1-neutral), it looks like Hot2 and Neutral have been reversed. Shutoff the breaker, verify there's no voltage, open the outlet, and correct the wiring so you can dry clothes without getting zapped. In the end, you should have this:

You do have an open main neutral.
Turn off the main power now and call the utility. They will check to see if the problem is on their side of things or yours. I suspect yours though.
