It's completely dependent on how you camp. If you don't use your wastewater tanks, have a generator
and don't mind taking the truck into town to resupply, you can last years.
So, how do you plan to use it? I have a Bigfoot
, not Oliver
, but for reference, if I'm using my trailer like a house: taking a shower every other day, doing dishes, cooking, occasionally using the toilet, I can make it 7-8 days before my grey water tank is full, and black water is getting close. Propane
easily lasts me a month, using the water heater, stove and sometimes oven.
I have solar
, but I easily went 7 days once with no solar
, and my battery
did fine. But I didn't run fans and didn't need the furnace
Anyway, if you don't have a way to charge the battery
, then you're limited by battery
capacity and waste tank capacity. You can replenish fresh water without bringing the trailer into town. Same with propane
and food. But when your waste tanks are full, it's time to pull the trailer into town.
But it varies. You could fill your tanks then just stop using them. Go to the bathroom and do dishes outside. You can go indefinitely. So it really depends on how you plan to camp.
