In greater detail, I have a three year old type 27 battery. It is rated about 100 amp-hours. Kind of standard issue with a 25 ft. TT.
In the past we have found it will last about 2 days, since we only use it for our LED lights, water pump and of course all the phantom loads. All our other needs can be met with the propane.
As I stated, the only time I needed a extra day or so, I just ran a set of jumper cables from the truck to the battery and let is charge for about 20 minutes. Crude but effective.
🙂 We thought we would try a bit more non-electric camping, to see if we really wanted to do it or to take advantage of a greater selection of camp grounds.
I would rather not use my truck to charge the battery it seem like a lot of over kill so I though a small generator or solar unit might do the job.
At this point whether my battery is at full charge or near full charge makes little difference, just so it has the juice to power the pump and LED lamps for a few days.
We spent years tent and canoe camping so our TT is basically a tin Tipi for convenient sleeping and cooking.
