Posting a follow-up as a lesson learned for others and extending my thanks to those that reached out with suggestions. I called around and found most RV shops couldn't take my trailer for weeks. Mays RV service in Lewisville, Tx not only agreed to look at it the same day but had it fixed at a reasonable cost in 24 hours. The issue was, as most suspected, a rodent(s) got into the trailer and chewed a lot of wires and not just in one location but three different locations (including the electrical brakes connection) in the trailer. I'll be taking a more proactive approach to protecting my trailer from rodents.
