I bought an old Barth TC that I've gutted to repair a bad jack mount. I had to put wooden supports under my jacks to get this lift I needed to mount and unmount the camper when I bought it.

My Silverado is a 2001 K3500 D/A. The bed sits very high. What sort of jacks will give me enough lift with the old style jack mounts?

I am debating upgrading my jack mounts with some custom built ones. Given that the camper is striped down to the aluminum framing, that would be easy enough.

I don't want to order new jacks and find I need to lengthen them.

Finally, I am debating manual versus electric. Manual is cheaper and mounts to my existing mounting points. My present jacks seem a bit wobbly fully extended.

Electric seems like a good idea because I can lower all of them at the same time, or raise them at the same rate, and it would be faster, and gets the ordeal over with quicker.

My main concern is safety. I need strong reliable jacks that will hold up.

My second concern is mating them up to my frame secures.

Any advice would be welcome, particularly from those with older campers and those that have modified their campers.
