This was actually while in travel. Worrisome at the time, funny later.
After crossing the TX panhandle on I-40 and into NM with temps running 105 and above, we pulled into a rest area west of Santa Rosa to let the dog out to do her business, and ours while we were there. After 15 minutes or so, got back in the truck to leave. Put it in gear, hit the throttle, and no go. What? Tried again. Barely moved. Put in reverse, barely moved.
Oh, man! Transmission out? Tried again. Noticed the truck trying to move, but 5er not moving. Ah! Trailer brakes must be locked up. Checked emergency breakaway switch. Pin in place, but I pulled it out and reinserted. Still no go. Brake controller maybe? Pulled the cord to the trailer. No go. Turned the 12v disconnect switch. No go.
About 6 PM on a Friday afternoon and not long til dark and in a small rest area in a very remote area. Called an ERS that came with an extended service plan with the trailer. They were useless. Looked up phone number of local sheriff department. No answer! Looked up phone number of Santa Rosa police. Called and asked if they knew of an RV repair shop. "Yeah, but there are all closed now." No other offer of help. OK, time to panic.
Noticed an older maintenance man picking up trash around the rest area. Asked him if he knew of anyone who does RV repair. He spoke english with a fairly strong spanish accent. So he gets on his phone and begins speaking to someone in spanish. This makes me a little uneasy as I have no idea who he is talking with or what he is saying. But he hands me his phone and I am speaking with another obviously spanish person on the other end, but with less accent, and explain my problem.
"Ah, your emergency breakaway pin pulled." No, already checked that. "Your brake controller must have failed and holding the brakes." No, already checked that.
"Are you parked along the right side where the semis park?" Yes I am I said, wondering why that mattered. "Your tires are stuck to the asphalt", he said. WHAT? "Yes, your tires are stuck to the soft asphalt where the big trucks park. Get in the truck, put it in gear, and hit the throttle hard". I told him I already tried that. "Listen. I have made more $300-$400 trips out there than I can count for that very reason. It is downhill backwards. Put the truck in reverse, and hit the throttle".
I looked and, yes, it was slightly downhill going backward. He was obviously familiar with the rest area. Got in the truck, put it in reverse, hit the throttle fairly hard, truck hesitated a moment, then started rolling backward.
Got back on the phone and thanked him and ask how I could pay him. He said to just give his friend a little tip and be on my way. Gave the guy $20. He was happy. I was happy. Best of all, DW was (finally) happy. Apparently the guy just did not want to make a $300-400 call on a Friday evening. Or, hopefully, he was just a good guy. And what were the odds of finding a maintenance worker, picking up trash, who knew an RV repairman, who knew what the problem was? Someone was looking after us that day.
SO. If you ever travel across TX panhandle into NM during a very hot summer and stop at the rest area west of Santa Rosa, park on the left side, not the right side where the semis park.
