There is 122 gallons beneath the cockpit and cabin in three fuel tanks. The "original" Howards - the 8,9,11,12 - has a different gear - narrower, but much stiffer - they sit higher/stance is different. Even though the gear is narrower, the airplanes don't have the nasty ground habits that accompany the 15. I've been told that they are better in ground manners than even a 195 - but I don't know as most have been converted to DGA-11's and they are "rare" to say the least. Even the DGA-6 (Mr. Mulligan) has better ground manners than the 15. The DGA-11 has a 450 Pratt like the 15 does, but you will notice below they are not nearly as "fat" looking around the middle, and you can see the difference in gear.
I introduce the much sought after, yet often unobtainable DGA-11 (cc
@knot4u - I believe at one point Don Dickenson owned a DGA-11 but not sure. I know he had a Spartan Exec in addition to his DGA-15). Notice the "slimness" and the taller, narrower gear.

And now the younger, fatter, ill-mannered sister the DGA-15.

The 11 was much faster on the same power, flew better, and was sexier looking.
But don't let hangar flyers scare you off the Howard DGA-15. Yes, it's not as mannerly as the previous models. No, it is not impossible to land successfully. My grandpa owned his from the mid-70's till he died and never ground looped it. Nor his Wacos. The only airplane he ever groundlooped with me in it was his Aeronca Chief. (long story - no damage and I flew the Chief an hour later). He said the airplane (Howard) kind of made him feel a bit like when he was flying a T-6. He said as long as you always understand the airplane is going to try to make a fool out of you at random times and never hesitate to go around you'll be good.
