We just got back from the cabin and doing some "practicing" and tinkering. I received an email from Petersons in UT., and they have a maintenance manual they say will work for me. I will get it on the way next week! As for the trailer, it was explained to me that the power company used it to haul the cat to wherever it had to go. It was sold as a package, so I had no choice. The seller estimated the package at 9-10,000 lbs. The truck is my godson's. It is a F250extra duty with a 7.2 (?) turbo diesel. The seller set up the trailer to be towed with this vehicle. It has a pintle hitch. The trailer has electric brakes that are apparently activated by the electrical connection to the tow vehicle. The trailer is 8' wide. The cat is 118" wide. In WA. all you need is $10 permit, flags, and wide load signs to haul the unit. (102" is max without a permit) On the way up we stopped by a closed scale and total weight was 11,700#. On the way back the trailer came in at 3700#. We do not plan to tow this unit as a RV. It will stay at the cabin unless there is maintenance to be done at home. At most it will be towed 2x per year. On the climb up the pass he kept it at 2800 RPM and said he had plenty of power to go if he needed it. The truck dropped 3" when the trailer was attached. I followed, and there was no whipping of the trailer or out of control moves on the trip. Other than knowing he was pulling something big, he said it went very well. Now you know what I do. Thanks again for all your help.
