34 hr reset?

It was soooo windy yesterday... it's not fun to drive empty with gusts of 40+ mph... on a kinda busy narrow 2 lane road full of bumps and patches...
Parked here since last afternoon... Truck kept bouncing side to side with the wind all night long... All quiet today. Beautiful sunny out there... but still cold (for me)... Don't feel like walking around.... maybe later will jump on the truck and clean the windshield...

Spent the day in Denver yesterday visiting friends, dinner with my son, his lovely wife, and my grandson. Liberal KS, got dead cows on arrival. Of course, the truck god has to rain on the ol' parade. No. 1 injector is unhappy about something. It's running a little rough at lower power levels.

One of the reasons I pull tank now....

OCed and MEANbeanRocks Thanks this. -
Well... but what about the surging, the splashing? I heard that tankers can roll over easily because of the high center of gravity and the liquid movement... That's one of the reasons why I don't drive tankers...
-
The surging depends on the weight of the product per gallon and how full the trailer is. Its not as bad as livestock or swinging meat.Rocks Thanks this.

Eloy Az. Warm and sunny. Nice beer drinking weather , in fact I might go get one seeing as my day is done and I don't have to get going until tommorow morning!

EDIT: I see Cowboy beat me to it while I was composing my treatise!
It really depends on the type of tanker and the product density, Rocks. A fuel tanker full of gasoline is no big deal, the same tanker with diesel is a little trickier. The trailer with gas has a slightly higher cg, but because it is nearly liquid full there is little change in cg as the truck maneuvers. The same truck, at the same gross weight, loaded with diesel has a lower cg, but because it is only loaded to around 80% of liquid capacity, it can slosh around a bit more, moving the cg to the side and up in corners. But this is still an easy critter to tame, compared to the unbaffled trailers.
This fine fellows can be a handful because they often are loaded with very dense liquids and are only in the 50-60% liquid full range. So the cg can shift even further to one side and have a greater height change, plus you can get very significant front to rear shifts as well. It's all about being smooth with tankers: your throttle and brake inputs are gradual increases and decreases (timed to the slosh with the really ugly loads) and corners are eased into and out of to minimize the accelerations(+ and -) the liquid is subjected to. The jerk and jump of the truck stop cowboys is the last thing a tanker yanker wants.
The cg of most tankers is actually fairly low; the pnuematics and high volume (10K gal) chemical tanks being the exceptions. It's kind of counter-intuitive, but because you are usually loaded to gross, the lighter density products are actually the ones with the highest cg's because there is more volume of product. Think of a reefer: a meat load has a much lower center of gravity than a load of processed food that weighs the same but fills the trailer to the ceiling.
Once you're an accomplished yanker, and smooth is an understatement about your driving style, the only time the surge and splash are a major issue is during emergency maneuvers (usually caused by stupid people tricks, of course!) when you really have to be prepared for the forces your movements will initiate behind you.
And since this is "Where are You?," I'm in Hutchinson,MN fixing to sneak up to St Cloud to get a shower before I finish loading my ND cars tomorrow. And the pizza and the sandwiches at Nelson's Petro are dang good eating.Rocks Thanks this. -
#### Hammer u really have been out here 2 long such sophisticated infomashion and such smooth vocabulary---but have u ever hauled swingin dresses on a reefer?? Now that is an unstable barely takes le beast!

Couldn't help it im tired and ain't mess wif u in a spell--b safe
Oh Produce Mkt in the Gateway--waitin on someone to got their dead ### to work
