TC sways jacking up and down. will I ever get used to this?

Deb, the jacks that were used on your Amerigo that mount under the wings aren't known for being the most stable. The design of your camper doesn't lend itself to installing corner jacks like most have today, so you might want to consider a Stable Lift system.

My first truck camper had jacks like yours and I hated them.
