My 67 H holds exactly 30 per side as well.

Don't believe everything that the manufacturer tells you about your airplane.

FWIW, I upgraded the original cessna fuel senders to the McFarlane senders, which resulted in a significant improvement. A few years later, I thought there could be further improvement and upgraded again to the Cies senders, which resulted in an additional slight improvement. Regardless of which sender one opts to install, they only output reliable information based upon an accurate initial calibration. Most fuel pumps state there can be up to a 5% error. Don't know if you've calibrated your pump, but if not, there is a possibility you pumped an additional 1.5 gallons (5%) in each tank which would be close to the specs. Bladder installation can account for small errors in capacity as well. Finally, during the initially calibration, you may have noticed small fluctuations on your engine monitor's "fuel meter" even after you let the tank settle. Depending on what base value you select for a given quantity, those fluctuations can account for small differences as well between the actual quantity versus the stated quantity. There is also a difference in stated quantity in level flight versus 3 point. If you calibrated the tanks in "level" flight, I've found the fuel capacity can vary up to 2-4 gallons greater in 3 point. I have a jpi 930 for my engine monitor.

My tank capacity including unusable for a 75 185 is 84 gallons. I've drained my tanks several times and refilled them to at least 42 gallons total per side depending on if wheels or floats are installed. Regardless, I always use a fuel stick to verify what is actually in the tanks compared to what my engine monitors states and start investigating if there is a discrepancy I didn't expect. Take care.

OK, I will jump it. Mine was weighed. 1979 180 with float kit, Full interior short rear bench, extended baggage.0-520, Light weight Starter and alternator. 88'' mac 401. Full glass no vacuum with auto pilot, Wing X , sportsman, VG's ABW 10' with Desser 31's (50#'s more than 8.50') and BBW. I do have the Gross weight increase to 3,190.

Weight 1,898.5, useful before my big belly 1291.5#.
ARM 35.37
Moment 67,155.795

1978 185F, with 3 blade McCAULEY AND WING X and basic panel, empty weight on 700 TIRES - 1860 lbs.
On EDO 3430's, empty weight - 2161 lbs.

Just re-weighed it last year so it is correct.

1960 180C, at 1603 pounds.

Pretty much as out of the factory except, some instruments, radios, now small alternator, tires 8.50´s, back seat bench style.
Its the third of the row on my pic.

Fresh off the scales today at 1718#, weighed with 12 qts oil, fuel drained at gascolator and sumps.
1953
29" ABW, 10" tailwheel, airglass extended baggage, 185 gear legs, sportsman cuff, 6 bolt wheels / Cleveland brakes, float kit, IFR panel, no vac system, 86" 401, heavy case 520, dual exhaust, p-ponk gear stiffeners, remote oil filter, Selkirk interior panels, atlee dodge jump seats, sport aircraft seats, FRESH PAINT!
IFR panel is Garmin 430, 2-g5's, Garmin 225, sandia stx165, audio panel, jpi 830, clock/usb charger, and all the steam gauges.

Also did an actual electrical load analysis last week, EVERYTHING in the plane turned on AND transmitting on both radios, 28.5 amps draw. LED everything, but still running a generator.

You can't put FRESH PAINT in all caps and not post a picture. Cruel.

Hopefully it comes through.

Nice!
And not all that heavy either- considering all the mods.
Good show!

1965 185D, IO-520, 88" two blade McCauley, float kit and ski hardware, firewall battery + Atlee extended baggage. Rear bush seats, basic but functional panel. Long range tanks, with VG's but no STOL kit or wing X. on 7:00 wheels, the amended W&B puts it at 1756. Has not been on scales anytime recently. On C3200 wheels skis its at 1904 (no tail ski) and Edo 3430 floats at 2120.

Wishlist includes a Sportsman and two Garmin G5's to replace the entire vacuum system.

Just finished new motor and prop install on my 1955 180, then freshly weighed in at 1802.

New motor is amazing, 149 indicated, TAS 163 give or take a couple at 23" and 2600 RPM at 75% break-in

Looks good!
3 blade Hartzell prop ...is that the Voyager?

Yes 86" voyager. Next is 185 legs and paint

Your plane looks beautiful. Why spare any expense - save some weight and get the Titanium legs. I am going that route in my 180. Tom (Tailwheel) is in the process of getting a new STC for Ti legs that only weight 21 lbs each. I believe the 185 legs weight 37 lbs each.


Josh

Would love to but at 18K I think LR tanks are more in order. Then a paint job

I'm pretty sure that TLGW takes stock gear legs in trade toward the titanium legs.
So if you can't find the gear legs you need elsewhere, you might give them a call.
They also recondition gear legs.

Well, I'm really glad to see some of you folks are single handedly supporting the aircraft maintenance and upgrade industry......Wow!

Finally got mine weighed after a bunch of STC's - 1631lbs with bladders emptied at sump drains. IA called it 1661 to account for the unuseable fuel but there was still some fuel in it. Somewhere in between there lies the real number but not too bad for a big prop/ABW/BBW airplane.
