Spring of 2012, I had ERS tow me off a mountain pass. The operator or tow company did not understand truck camper or over 10,000 lbs gross weight. First they sent a small tow truck that could do nothing but waste time walking around, then they sent a roll back that got me to a parking area after I removed my SuperTruss to clear the loading angle (sat 12'+ high on top of the rear deck), and finally sending a MDT that disconnected my drive line (even though I could put the manual transfer case in neutral for towing) and pulled me to service using a stinger. I ended up exaggerating my vehicle as a 25' Class C RV at 13' high and 12,500 lbs to get the right equipment to me.
The whole process took 12 hours from my initial call to the final drop in the service lot. All three dispatches were paid by ERS but I had to pay up front and submit for reimbursement.
