If I had this information before I left it may have postponed our trip to the local Rv park about (10 miles). But because my main issue was the charging of these batteries I just didn't realize it. The fact that I had pulled the pin (breakaway) didn't occur to me until Sat night at the park.
Just to be clear I aways check my bakes when I hook up and start down the road. I get up to about 10 mph and use trailer brake to stop my TV. When I tested my brakes Wed upon departure the trailer brakes functioned normally and away we went. If they hadn't operated as expected you can be assured I would not have left my house and would have been asking the question on here as to what happened Our trip was roughly 23 miles round trip and thankfully was uneventful.
To the comments about wheel chocks I had already stated that I used them, I just pulled the pin because I thought hey why not be extra careful...:face palm:

Flybouy when I pull my drums off this Sat. and look at the magnets what should I be looking for? Thank you for sharing your knowledge!

I would disconnect the wires and check resistance, they should each be close in value. Visually check the wires for any obvious signs of heat. Overheating of the wires can cause the wire insulation to appear discolored and the insulation may feel loose on the wires. The bare ends of the wire can appear discolored as well Check the magnets for any signs of the insulation bubbling or looking burned or appearing like black flaking paint. If in doubt replace,they aren't that expensive. My driveway also is pitched towards the road. I use 2 rubber chucks tied together with nylon rope. I place the chocks back to back in between the tires ( tandem axels) then put the truck in drive and drift forward to "set" the tires against the down hill chocks. This makes disconnecting and jacking the tongue as safe as possible. Hope this helps. Let us know how the inspection goes.
