Coldest day here I came home and the heat in my house had stopped working. Reset and it fired right back up and has been OK. Don't know why it quit, fuel is treated but maybe it gelled up any way. My rollback hasn't run in days, it starts and runs a few seconds and stalls. Fuel has been treated, I put enough treatment in for 100 gallons in a 30 gallon tank and we tried 911 then too and it is still not running. One other rollback was hit by a drunk driver and ripped the rear out of it and broke the leaf springs among other damage, I have that almost finished now and we have a new rollback but it isn't registered yet so we are down to one rollback so I am running my ass off trying to keep up with the police calls and still get regular towing done. So the cold has really thrown a wrench in the works.
