Assuming a 12v lifepo4 battery has been fully charged(*) to 14.6v (100% SOC), it can take 36-72 hours to drop to its final 100% SOC resting voltage of 13.4 - 13.6v (exact voltage varies from battery to battery). 36-72 hours assumes zero load on the battery and all charge devices turned off.
There's nothing you can do to speed up this specific process. Applying a load to drop the voltage quicker also discharges the battery to less than 100% SOC. Not sure what would be gained by doing this.
(*) Fully charged defined as 14.6v applied to the battery with zero flow of charge current.
@MadCityJack What you're seeing is normal. The level will rise when hot (because the glycol expands) and lower when cool just like antifreeze in your car.
Personally, the 4500 tow capacity would give me pause, as you are pretty close to the 3900 Tab fully loaded weight. Others may be less concerned. I feel very comfortable towing my 2021 400 with my Jeep Grand Cherokee which has a towing capacity of 7200, V6 and factory tow package. Average 14 mpg.
As to a backup camera, we are downsizing from a 27' Lance to the Tab. My partner is not very good at directing me while backing up, so the camera saves the marriage.
@AnOldUR As I mentioned in my previous post here, the term surface charge is a term from lead acid battery charging chemistry. A more complete explanation is free electrons accumulate on the surface of the electrode plates during charging. This gives a false (high) reading as to the actual charge condition of the battery when tested with a meter (hence the term surface charge). I thought of this when reading about your experience. The procedure I learned in an ASE training school (decades ago) to correct this condition before testing with a meter is what I went further on to briefly explain in my post. I haven't yet mastered the intricacies of lithium battery chemistry. I have only a few months experience with them so far, so do not truly know if this condition exists in them. I was trying to offer a suggestion based on associative reasoning (a common method of problem solving in my world). In any case, based on the chart in your first post and subsequent reported data it appears your batteries may currently have too many electrons sitting in them. I'll refrain from dipping my toe in to your pool here anymore as I don't think I helped. Best of luck with the shunt.
As mentioned above a lot of it does depend on the type of dog you have. We've always had dogs in our lives. For us it's just hard to not have a companion such as a dog. In the past we've always had very large dogs. However just over 4 years ago we rescued a little 10lbs chihuahua. Never having a little dog we actually were not sure what to expect. The only thing we did know prior to taking him home was that he appeared to be very quiet and calm and was effortless to walk. We soon learned that he was honestly the best dog we've ever had.
Do to his demeanor and size he is a joy to travel with. We never have to board him anywhere. He always goes with us camping and we take him hiking as often as we can. He is good for 8-10 miles of hiking. In the summer months if we go someplace we can't take him we leave him in the trailer only if there are hookups so we can run the AC. And even then it's not for more that 1-2 hours. If we go into town we usually take him with us and walk him around or leave him in the car for very short times if the store or restaurant is not dog friendly. But we've noticed that more and more stores are actually pet friendly so often we can take him in with us for shopping. And honestly if you are carrying a very small dog in a store it is less likely to be noticed or cause problems. We also have a backpack that he can travel in. We use that when we go cycling so he too can enjoy the ride and sometimes we use it when walking town and going in and out of stores. If we go someplace where we absolutely can't take a dog we just adjust our plans. Take Yellowstone for example. Dogs can't really go anywhere outside a parking lot. In these instances we leave our camp, we camp outside the Park in a Forest Service CG, at about 5am and hit our favorite sites and board walks early in the morning. The benefits include it is cool enough that we can leave him in the car for an hour or more and there are no people out at that time. It is very quiet and enjoyable. And if it's something we can't make work with having him along then we just do not do it.
So as you can see the type of dog makes a big difference. Having a small, quiet, non-destructive dog that you can carry and take biking with and is just as happy sleeping as going for a hike makes travel so easy and not stressfull. Each dog is unique and you just have to cater your trip to the dog. I recommend trying to find a dog that fits your lifestyle over the reverse. There are lots of choices out there.
