We have a 34ss and tow a jeep Liberty.
I have learned the limits of the engine/5 speed transmission the hard way.
Leaving Needles going to Barstow is a long grade on I40.
I wanted to use the horsepower curve so I turned od off and ran the engine at about 2900.
The engine didn't go to the red zone, but the transmission did. I guess the input shaft got hot enough to damage the seal. The hot fluid smelled up the unit. I now have a sometimes recurring problem with transmission fluid odor. I have lost a modest amount of fluid over the last 20,000 miles or so. I think I need a new front trans seal.

If I turn the od off and run 2400 - 2600 rpm the temperatures are manageable for extended pulls. If the trans shifts down, I only let the engine run up to 3000 rpm for a minute or less, depending on the transmission temp. The trans temp guage lags the temp at the input shaft or trans hyd pump.

Wish I would have known.

Agree, and that goes for the Genset too.

If you're going to pick one or the other, and it's not going to get started at all during the winter, change it after. Otherwise, next spring you'll be driving around on oil that's been collecting moisture all winter. But if you can, I would start it at least once a month and let it warm up fully to keep the internal part surfaces covered
