Newbie battery and solar power questions

Good morning all.....and sorry for the long post

I realize that this thread is mostly directed at the 320, that said I thought I would share my experience with our new 2021 400 BDL.........we took possession of our new caravan in mid July, since then we have spent 32 nights and only one night was in a campground with hookups, the other 31 have been totally off grid, with the longest single duration beeing 14 days

Both my wife and I are very accustom to "boondock" camping as we spent many years with our tent (and supplies) on the back of our bikes all over Western Canada, South Western USA, and all of the Baja........however, now with the new T@B we have become, well, let's say SPOILD!!! and never really try and conserve energy much, and so far have had no issues. So just a couple points for those asking "how long can I boondock for"

As many have already said.....prechill the fridge, I normally will plug in at home for min 24 hrs. at around ~4 setting, load the little freezer with 2 ice cube trays (that I modified to fit), and a small baggy of ice, then load with supplies and turn to ~2.5, we are so impressed with the little 12v fridge, both energy consumption, and what you can stuff in that little guy. We also carry a small 3-way fridge in the back seat of our pick-up plugged into the 12v receptacle while on the road, once the Walker tent is set up it goes in the tent with an extended hose outside to a 20 lb propane bottle (as a note....we have used the same bottle all Summer, so 31 nights boondocking) and I just weighed it, 26.5 lb, so ~6lbs left.......very efferent, as it has been extremely hot this summer

As for battery power, as we are normally in non regulated camp sites, so we always try and park with the back of the T@B facing SW, for greatest solar absortion, and as stated above we have become spoiled so we are not real great at conserving .......we find the 12v fridge is very efficient, and we try and keep stuff that we use regularly in the 3-way portable in the Walker tent to lessen the door open/close on the 12v but that is as far as we go for conserving energy, I have mounted a Sirius radio in the cabin and pick it up via BT on the Jenson, this we run ~6 to 8 hr a day (and mostly at night), that said should we have a cloudy day and battery bank is not full we also carry a small BT speaker and play the downloaded playlist of my phone, and beeing were we normal camp there is no cell service so not much need for recharging. Our vent is always open but very seldom use the fan, as we are normally outside, and do most our cooking in the Walker tent, only time the fan is used is if one of us needs a nap in the afternoon after a hard day of fishing😀 We also carry a 10" (rechargeable) battery operated fan, that can be used inside/outside and is wonderful. If we have a good sunny day we even use the inverter to make toast for breakfast, and my wife having long thick hair will use the hair dryer couple times a week. The Alde heater does not use much power at all (again been hot this summer, but does cool down at night hear in the mountains) All this said we just monitor the victron to insure we don't go below 12v (always check mid afternoon to insure enough energy for over night) and have not had any issues power wise, and as mentioned above our longest trip was 14 days........we are going to purchase a "suitecase" solar panel for those overcast days,  or times when the best camp site is in the trees, as we all know these sunny days will not last

As for the 3 holding tanks, we always try and camp by a creek or river, so re-filling the fresh water tank with the new Nautilus system is as simple as it gets, plus we carry 2 (5gal) drinking water jugs, the 2 drinking water jugs last us ~10 days........the grey tank, we only use biodegradable soaps, and never put food or grease down the traps, with the 2 of us, and only short showers every other day, the grey tank lasts ~5 days, in our area we are permitted to dump grey water in the bush, I try to keep it aways from our camp site (lessen the bug attraction) and never close to a water body, but check with your local area as I am sure many places are different........as for the dreaded black tank, again we get ~5 days, this we carry a 5gal tote to empty, many places we camp at have a pit toilets close by, and here we are permitted to dump waste in them, that said even if a pit toilet is not close by a nice scenic drive to the nearest town every 4 or 5 days is not that big a deal as the wine supply is normally getting low by this time😀😀😀

Again sorry for the long post, just thought I would share a.........."just go and do it" prospective

Have a wonderful day
