Nice tc with small water tank, water heater is only 4 gals. (quick showers) smaller fridge...but at the end of the day...it works .
Being that it only has one propane tank , I am not sure how you would know how much gas you have left. It might have a gauge, if accurate , it's fine. If not , you have some options.
Carry a second tank or better yet, use an adaptor that allows you to plug in a portable one pound cyl. to get you through a night or day.
also avl at Walmart for 25.00.
