Best shock for a light weight pop up truck camper

I'm another one that drops the front jacks to stabilize. But mine are electric. I can see that being a pain if yours are manual unless you're staying put for a longer period.
Just throwing this out there, others are welcome to schinto on the idea....but what about a pair of jack stands under the tie down arms? Or even some wood blocks and wedges. You wouldn't be putting huge forces on them and it may be enough to take the rocking out.
