Hooked up and parked in front of the house, getting ready to leave the next morning. Unplugged the trailer so it wouldn't drain the truck battery overnight. Next morning, pouring rain, took off. On the freeway a few miles from with the headlights on. Notice the lights are not on, on the trailer. Forgot to plug it back in; I blame the rain.
Got to the campsite. Backed in. Leveled. Unhooking, found the emergency brake cable never attached to the truck.
Mid trip. Stopped and filled the trailer with water. Went into the trailer and got something out of the 'fridge. Got to the next campsite 200 miles later. Food all over the floor.
Now. I check the interior. Windows, vents, cupboards, refer, water pump, heater, water heater . . . Okay I'm done. DW - go check the interior. Same on the exterior.
