donno0128 - I know there is a difference between static load and dynamic load.
But what I am thinking in regard to pulling a fiver is that it is the reverse of normal situations.
When I worked in a warehouse, many, many years ago, there was a loading limit per square foot for the floor of the warehouse. When I operated my electric forklift carrying a pallet of 55 gallon drums, and the drums were full of small steel parts or fittings, based on the combined weight of the forklift and the load itself, I exceeded the floor's limit for certain. But I was told that as okay because it as a dynamic load, not a static load. So in this case a static load was more stressful than a dynamic load.
But with a fiver, when I lift my front jacks the truck barely drops at all. So the static load is no problem. But if I am going 65 mph, and bounce through a lane shift as part of road construction, I tend to knock the dust off the helper springs. So in this case the dynamic load seems to be more stressful than the static load.
That is why I wondered if I could baby it along and not do any harm.
