All good questions.
"•What is the total weight of the Cub with all the fuel passengers and baggage?"
Myself - 140 (True Weight)
Heidi - 123 (She's about my height and 123 looks good on her)

Miniature Pincher Puppy - 15 (He's been a little heavy lately)
So normal TOW with full fuel, oil and my little crew is 1123 lbs.
On the couple of long haul legs where I was concerned about fuel, exchanging Heidi for the two 5 gallon gas cans gave me a TOW of 1060 lbs.
"•What is the cruise altitude you fly at?"
Normally as low as possible. I believe that the Cub is designed for maximum fuel/power effciency at fairly low altitudes, so I try to fly within the 2000' range when ever possible. It's my understanding that even though the Cub will fly much higher, you don't actually gain anything in performance using the stock combo of propeller, engine and carburation. I will however, go for extreme altitudes, 8000' or more when I have a long distance to cover and the weather is showing a good chance of healthy tail winds up at those altitudes. Then in a case like yesterday evening's flights along the Caucasus Mountains, I was flying at 4200' just to make sure I didn't hit anything in the dark.

"•What is the RPM setting you use?"
By the book normal cruise RPM is 2150 and I try to live by that rule as much as possible. As soon as the Cub breaks ground on take-off I pull the RPMs back to 2150 while trying to establish a climb at 50mph indicated. I make tiny adjustments as needed to keep the 2150/50 settings until I reach altitude.
One trick that I think??? that I've learned is on some of the longer open ocean legs, I go for higher altitudes with good tail winds and then I'll pull the RPMs back so that they are hovering just above 2000. It seems to work as sort of flying a kite routine. Instead of using the power of the Cub to pull itself from point A to point B, I'm letting the wind blow the aircraft to where I want it and using just enough power to keep the aircraft flying and the engine warm. I'm not sure how scientific that approach is but it does seem to help stretch the fuel out.
"•What range do you get from the Cub on those settings?"
Notable longest times aloft on single legs so far:
3:13
3:51
3:13
3:55
Single longest time aloft I've had in the Cub was 4:52. This was an early endurance test for the tour. During the test I was in an almost continous slow climb until the fuel ran out. It then took forever to glide back down to land.

Notable longest non-stop flight legs so far:
BGGG - BGBW 250nm
CYVM - BGSS 242nm
EKVG - EGPW 244nm
EYVI - UMGG 240nm
Island Refuel - BIPA 302nm
