How long does your propane last?

We are back from our 25th wedding anniversary trip to Israel, and had an absolute blast!! 25 years with tyhe same one!
I have a design question: There is very little difference in price here between a 6 kilogram and 10 kilogram propane bottle. I am assuming this is close to about 1.5 and 2.5 gallons capacity (?)
1. What size of tank are you using?
2. How many days does it tiìcally last?
3. Do you have a stove and oven, or just a stove?
By the way, I plan on using the Mexican Flamineta propane stove/oven on ours. My goal is to get about 5 days out of a tank, as our missiojns trips usually start Thursday morning and end Monday evening. We are considering maybe 7-10 meals prepared in the Teardrop during a typical trip. But we are also concerned about exceeding the recomended toungue weight on the VW bug (old beetle), which is just 90 pounds.
Blessings!
