I have a Valley/Husky (same thing)and have had no problems with it. They are manual, no auto sliding of any kind. Some don't like the bar type that slides in front of the kingpin, but it sure is easy to see if you are properly hitched. I've got no complaints and you can remove it yourself since it is a two piece hitch.
Hydraulic fluid is hygroscopic. Means it absorbs water from the air. Some can absorb enough water that the steel parts in contact with it start to rust. Ergo, why you change it periodically.
Not all hydraulic fluids are hydroscopic. True petroleum based oils are not. Even transmission fluid is not hydroscopic. The water comes from head space in the reservoir and temperature changes which causes condensation to form on cooler surfaces. If you get a cap for your reservoir that prevents moisture from entering, you won't have a water problem.
Red Light Camera's ----They are ONLY used to enforce Red Light infractions. Nothing else and yes, that story has been out there for a long time. Not true. Doug
Not true, those cameras in Pima county were used to ticket speeders. They were radar operated and triggered at 11 mph over posted speed limit. They have all been removed now because the only people making money was the 3rd party running the system. And, in AZ, you cannot get a ticket for not wearing a seatbelt UNLESS you get stopped for something else and your not wearing one.
Thanks for your opinions. I too, have always used T/H anytime the 5er is moving. But I had to move my trailer today and I was on a flat/level stretch of road and it got me to thinking if T/H was really necessary under those conditions, especially given the MPG you lose. Just curious what others did. Thanks.
The only difference between tow/haul mode and regular on your GM is the shift points are higher and the torque converter locks up sooner to help keep the ATF fluid cooler. On a flat, level road, it will shift to top gear at the same point you would without it on. MPG loss should be miniscule on a flat road, if at all. Yes, you lose some MPG when starting because the shift points are higher, therefore the engine revs higher. I forgot to engage T/H once in NM on I-10, didn't notice a difference in mileage, but my tranny fluid was about 10 degrees higher than normal when I tow my 5th wheel.
I don't know what alignment shop you went to, but if they have the equipment, a 4 wheel thrust alignment would tell the person if your rear axle is "crooked" as they will not be able to get the rear wheels aligned correctly with the front. Hard to explain unless you have worked with the equipment or are familiar with how it works.
