Help - jacks are draining my batteries

My 2020 camper came with HappiJacs which consume a ton of power from my 2 deep cycle batteries. Once the batteries are drawn down after removing the rig (3000 lb dry weight) from my truck, it's nearly impossible for the generator(s) to get them back up to an acceptable charge while camping so we're really limited in what we can do and for how long. We have plenty of power as long as we leave the camper on the truck, but that's highly undesirable. I have tried loading/unloading with gens running; have tried using power drill to get legs to/from the ground; batteries have been load & spec gravity tested several times and are fine; adding a 3rd battery and/or increasing battery size is not an option due to the size of the battery compartment and no other exterior storage options; the rig's entire electrical system has been diagnosed by a tech and it's fine; contacted the camper manufacturer and they simply shrugged their shoulders and have not offered any insights or solutions; adding solar would be an absolute last resort.

Do any of you experience this? How do you get around it? What input/suggestions do you have for me to solve the power issue? Do any of you have an alternative method for taking the camper off the back of your truck? Anybody tried an impact driver?
