We can go 5-6 days drycamping, but could probably stretch it a couple more days if we wanted to REALLY conserve.
Here's what we do:
- We use paper plates and paper bowls to reduce dishwashing water use. We keep a big plastic trash bag in a compartment for the used paper goods.
- I use an electric razor, so no washing of a shaver is required. The electric razor can go many days without recharging.
- We use electric toothbrushes, but they can go many days without recharging.
- We brush our teeth out of a paper cup ... we do not run the faucet for teeth brushing.
- We shower with constant ON-OFF switching of the shower head for good fresh water conservation. Sometimes we even take sponge baths, instead, for maximum fresh water conservation.
- The grey tank fills up first ahead of the black water tank, but .... we off-load the grey water tank into the black water tank to extend grey water tank use.
- We carry extra water for drinking and sometimes bring along a couple of 2 1/2 gallon store bought jugs of emergency water. We do not drink out of the freshwater tank, but we do cook out of it, even though the kitchen faucet has a built-in filter between it and the fresh water tank.
- We have two hundred amp hours of battery capacity for the coach (two 100 amp hour AGM dry 12 volt batteries hooked up in parallel). We do not have solar, but we have three ways of charging these batteries when drycamping. We can charge them using a very quiet little tiny 650 watt generator, we can charge them with the main built-in generator (which is pretty quiet, too), and we can charge them with the main engine alternator (which is the quietest but most expensive method). We carry about 25 hours worth of extra fuel along for the little 650 watt generator and run it about 5 hours per charging cycle every 2nd or 3rd day.
- We've had full LED lighting in our RV for years ... probably way before it became popular.
- Our widescreen laptop computer doubles as an appliance for movie and TV viewing, and it operates directly off of 12 volts so we eliminate the wasteful efficiency loss of having to use an inverter.
- Our phones charge directly from 12 volts, so no inverter is required.
- Our special built-in amplifier for long range cellular access in remote areas operates directly from 12 volts, so no inverter is required.
- We use the propane furnace fairly generously to be comfortable as if we were in our home. We set it at 60 degrees during the nights so we don't have to get up and travel in the cold to the bathroom in the middle of the night ... this also means less run-time of it in the mornings to bring the coach area up to temperature on chilly mornings. We block off the poorly insulated cab area of our small motorhome to help minimize the furnace cycles during both chilly nights and chilly days. The propane furnace has several adjustable outlets for maximum circulation efficiency.
- We use the air conditioning (powered by the built-in generator) as required for both warm weather surprises, and for flexibility if we want to intentionally camp in warm areas. We block off some living areas in extreme heat to minimize run-time of the air conditioner and the built-in generator. The air conditioner has several adjustable ducts for maximum circulation efficiency.
- We use a high volume, high efficiency 12 volt fan for cooling comfort in marginally warm weather. This can be used on an 12 volt extension cord to "get out of the coach" so we can sit outside on windless warm days under the awning to enjoy the fresh air and view. This same fan can be used outside at a table to keep the flies away if we want to eat outside on warm days or evenings.
- We did something counter-intuitive with respect to our RV water pump. We replaced it with a high capacity low-pulse-rate RV water pump and feel that this may actually be helping us to use LESS water. With the old pump we kindof tended to "run it more" to get the water out of the faucet or shower head that we thought we needed per turn-on cycle. With this new pump, we seem to be able to just touch the faucet for a split second and the water seems to be immediately "there" and "in full volume". We've made no measurements, but feel that this trick is probably saving on water usage, overall.
- We always travel as much as possible with all tanks full that should be full and with all tanks empty that should be empty, so that we're not taking any chances with not finding filling/emptying facilities when we need it. Our RV has plenty of extra carrying capacity for this.
After spending the money for our RV setup, we feel we should be able to camp in it anywhere anytime as if we were still in back in our home. We camp this way when drycamping as needed (and preferred), often in remote areas while rock hounding.
