Also, it’s not a common practice to use an electric drill unless your batteries are low or failing…Be advised that a Auto-Zone type carbon-pile load test is not always to be relied upon as a true representation of actual loading…If possible you could try measuring battery output (while under load) using a clamp-on ac-dc volt-current meter - make sure that your meter is ‘truly dc current capable’ and of sufficient amperage…A meter of this type is still cheaper than new batteries and should readily tell you what you need to know.. Also, when using meter in ‘dc mode’, be certain to position the meter in the proper current direction - follow carefully the meter’s instructions … 3 tons I am using all 4 jacks simultaneously. Maybe a little overly simplistic way of thinking about it (and also maybe a little out of my element here) but it seems like the same amount of power/energy is needed to raise/lower the camper, so whether you break it into pieces (1 or 2 at a time) or do it all at the same time (all 4 jacks) shouldn't matter all that much. If I'm wrong, and doing 1 or 2 at a time would help solve my problem, please let me know.Re: Help - jacks are draining my batteries wnjj wrote: bigfootford wrote: Depending on the weight of your camper the amps needed for a 4500lb camera will be between 35-40 amps to raise the camper.. The OP said the batteries are drained from removing the camper, which makes even less sense. Other than the initial lift off the truck bed, most of the time the motors aren't even loaded when running to remove it. I over simplified when I wrote that the issue was from removing the camper from the truck. More specifically/accurately, it's the round trip unload/load...then by the time we move to another camp site and unload again, it's toast.Re: Help - jacks are draining my batteries 3 tons wrote: Regardless of the seemingly recent shelf date on your batteries or the voltage readout (at best, a marginal estimator of true battery condition…) using only the principle of Occam's Razor (from afar…) I’d say (from same issue past experience…) the root problem is that your batteries are near dead, yet ostensibly appearing satisfactory per voltage readout - Try as you might, wet-cells can act like this - this very situation is NOT unique or uncommon, and is a precursor to an internal cell or post connector failure. The fact that the batteries ‘appear’ satisfactory yet are not (“say it ain’t so”!!) is from my perspective the true source of your dreaded frustration…JMHO 3 tons This would certainly be the easiest solution, but I can't help thinking (perhaps because I'm a little out of my element on some of this) that if they were "near dead" this would/should somehow show up, at least a little bit, on either the load test or the specific gravity (both were fine)?Re: Help - jacks are draining my batteriesThanks everybody for the feedback. I'd like to provide a little extra info for the two most common themes in the responses I have received: converter & batteries. The converter is a Progressive Dynamics PD4045 Mini Mighty, the link below is the manual. Maybe I'm missing something, but it seems to be "right sized" for the task & rig. I had an RV tech test/trouble shoot the entire electrical system to try and help figure this out, and he concluded the same and said that the converter is working as it should. So it seems counter-intuitive and unnecessary to spend the $ to replace it with a bigger/better/newer one? I'm also a little reluctant to rewire/install a bypass switch as some have suggested, as the jack manual specifically say not to do this. https://www.progressivedyn.com/wp-content/uploads/Support/manuals/110145-English.pdf The batteries (2 x grp 24 wet cell deep cycle Interstates) were new when I bought the rig (Adventurer 86FB, no slides, 3000 lbs dry, new as well) in May 2021. The date on both batteries is April 2021. The terminal connections are good, fluid levels in all the cells are good, so is specific gravity, and they handled load tests perfectly. I checked these myself, also had RV tech check them and took them to Interstate dealer twice. Every test/measurement says that they are fine, so it seems counter-intuitive and unnecessary to spend the $ to replace them? This is not a new issue. It's been happening since I got the camper in May 2021. I always leave for a camping trip with full batteries; we stay plugged into shore power when at home between trips during the camping season. I always load onto the truck at least 24 hours before we hit the road to ensure the batteries are topped off after loading. I've checked the charge plug from truck bed to camper, and it's fine. When we arrive at camp site, I unload right away using cordless drill to get the legs to the ground then using jacks from there (with engine running and gens running). Sometimes we load back onto the truck a few days later to move camping places. Gens are 2 new Honda 2000's and run great, I usually run them for 2 hours both in the morning and night. Sometimes the issue is a little better/worse depending on conditions and where/how long we camp. We live and primarily camp in Colorado, where temps can be 80 during the day but wake up the next morning in the 30's and need to run the furnace.Re: Help - jacks are draining my batteries ssthrd wrote: I leave both my camper and my trailer plugged in to my running truck (my cords are plenty long enough) until I get the thing where I want it. Then unplug and drive away............ No draw on the batteries at all as far as I can tell. Maybe your genny isn't large enough. I've got two of the Honda 2000 gens (they are new and in good running cond.), so that should be plenty big enough?Re: Help - jacks are draining my batteries 650cent wrote: Use a battery drill w/adapter to run the jacks down to the ground first. Likewise use the drill to run the jacks back up once the camper is on the truck. I'm doing that, but it does not seem to make a measurable/noticable difference.Re: Help - jacks are draining my batteries 2oldman wrote: Run the generator while removing the camper. That was my first thought as well but, unfortunately, the jacks only draw from the battery. So whether I am connected to the truck, gens or shore power while loading/unloading, the jacks discharge the batteries much faster than the truck/gen/shore can replenish.Re: Help - jacks are draining my batteriesRunning the gem while loading/unloading was my first thought as well but, unfortunately, the jacks only draw from the battery.

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?
