Depends on lots of factors with your truck configuration and how you use your resources, here are some estimates based on our way of doing things (these are quick rough estimates)...Thank you both. I am curious about the resource that is limiting when boondocking. Is it water / diesel / fridge and freezer space?
Greg thank you for taking the time to respond to these questions your answers are well thought out and very enlightening to those of us who are interested in these big vehicles. There are not many of you who take the time to respond. Cheers.Depends on lots of factors with your truck configuration and how you use your resources, here are some estimates based on our way of doing things (these are quick rough estimates)...
Our truck has 200 gal tanks for diesel fuel so assuming you have them full enough you should not be limited by diesel fuel for either heating/hot water or generator use if needed (lack of solar or use of air conditioning would lead to running the generator).
Our truck has 130 gal of fresh water but we have the capability to pump water from streams, rivers, or lakes if available. Depending on how you use the water it should not be the limiting factor. We don’t make much effort to conserve water and could probably go 3-4 weeks without getting water. We have a drinking water filter (Seagull) so we drink water from the water tank rather than carry bottled drinking water as some seem to do.
Our cassette toilet or our 23 gal greywater tank would likely be the limiting factor for us if we could not dump them where we are boondocked. We carry a spare cassette so we can go a week or so with two cassettes. Grey water limit is based on how many showers you take but normally we could go a week or so between grey water dumping. No limit if you can dump where you are boondocked. We typically are traveling enough to dump the cassette and grey water in pit toilets or dump stations. If you boondock in an area where you could dig a hole and bury the cassette contents and could dump grey water there would no time limit.
Food as a limit would depend on what type of food you carry and whether it requires refrigeration or not (we don’t hunt or fish so no option to obtain food while boondocking). The standard Vitrifrigo fridge/freezer used in GXV trucks is pretty good sized and you could easily add a chest fridge/freezer to get more capacity or select a larger unit to start with. If we planned to boondock for an extended period I think we could carry enough food to not have it limit our stay but there is a limit I suppose of maybe a month or so (longer if not as much food needing refrigeration).
Bottom line, if we planned to boondock in one place for a month we could do it without much effort and probably longer if we could get more water or work harder at conserving water or selecting the right food (not too much fresh food or frozen food) and having a way to dump the cassette and grey tank. In reality, we have never thought about this very much since we have tended to be moving enough to limit our stays in one spot to about 2-3 weeks in places with access to a pit toilet and then being close to places to get supplies. We could probably go longer than a month if we planned ahead and maybe made some changes to the truck configuration. In reality, our major travel for the first two years has been to Alaska where we have not done extended boondocking away from access to water and dump options.
And again, these are some rough estimates, maybe even WAG’s...
Thank you so much for being so generous with your time and effort. Two weeks is plenty for us so the truck is a good fit.Depends on lots of factors with your truck configuration and how you use your resources, here are some estimates based on our way of doing things (these are quick rough estimates)...
That is incorrect. The batteries are contained within the actual box that GXV builds so they are in a heated place the same as the water tanks. @gregmchugh however is far better equipped to explain this as I do not own one of these rigs.Greg I see your spending time in a cold climate. It appears that GXV places the lithium batteries in a unheated space. Any problems with cold weather charging?
Not necessarily actively heated...So the “garage” slash rear storage area is heated?
The move to someplace warmer is also our usual approach to dealing with cold and snow but our daughter had a baby in BC in January so we have been here for awhile.As a contrast to Greg's (excellent) outline, our truck is a little different in that our Webasto Dual Top is located in the rear compartment - otherwise called the 'underbed storage' area and has ducts that snake up to the front cabin area.
The main reason we had the heating unit installed into the rear area is (again) due to my height and the fact that our shower pan sits directly on the floor (vs a subfloor that lines could run under) it had to go in the back.
Not only does the webasto unit itself put off a fair bit of heat through its metal case - we also discovered that the ducting also put off a lot of heat as it carried the warm air to the front of the cabin. A little heat back there is good - a lot of heat isn't great. There was enough heat radiating from the ducts that we worked with GXV to have some insulated ducts sent over and we re-threaded the ductwork with insulation and now it's basically perfect with zero risk of things getting too cold in the storage area which is where the plumbing/water lines as well as the lithium battery is housed.
Our grey water tank is located as Greg described - in an outside storage cabinet- but since we virtually never camp in organized campsites, we pretty much always have our grey water valve open so no real risk of it freezing and having an issue. But it does have a heating pad under the tank to prevent freezing if we need it.
Probably the coldest we've been is zero degree weather for a short period of time and didn't have any issues but as Greg mentions, if you intend to be in sub-zero temps for extended periods you should take that into consideration and discuss with the folks at GXV to make the right choices. A perfect example of that is we chose NOT to get the dual-pane glass windows which are more thermally efficient than the plastic dual pane windows we got but we wanted some larger window options (and more windows) that would have made that choice a considerable investment that we didn't see the value. However, if we were going to spend long time periods in extreme weather conditions, I would recommend the high end windows for sure.
The way we look at it, if the weather is that crappy, we're just going to go somewhere the weather is nicer. Isn't that the point of having one of these?
