Which model to buy.

Yep, figure 150 gals@ 900 lbs, so you're left with about 500.

Regardless, I've been dissuaded by the local 337 A&P from getting into the P, in spite very appealing comfort. He put a number like 1.5-2x on the recurring costs (but I don't want to (re-)start those threads). So I'd be looking for that rare Turbo II, or putting up with hydraulic power-packs and doors that go like this <--[]-->.

I would agree with your A&P .

I thought the P models gross went up to 5100 lbs?

My T337D has a RSTOL increased gross takeoff of 4,700 lbs
About 3k empty, so about 1700 lbs payload.

Minus 128 gals x 6lbs/gal = 768 fuel, plus almost 1,000 lbs of people and stuff.

There was one trip to start the summer,
family of 4, (2 SMALL kids)
large afghan hound (skinny, but huge)
100 lbs of flowers,
two violins, a cello,
plus boxes of tiles to redo the kitchen
..AND a new kitchen sink.

I literally head everything in there INCLUDING the kitchen sink.
That was at gross.

And what mod allows more ?

(When I researched this, I found nothing but an empty sales pitch …)

Other than the proprietary increase that Air Scan did the only increase I am aware of is Robertson STOL. This was an increase gross weight for take off but defaulted back to certified gross weight for landing. It's a lot more work and money to change the weight for landing than it is for take off. VG's on the Skymaster did not gain any GW like a lot of other twins benefit with. There are some early (pre 73) Turbo models that have R-STOL but very few later model Skymaster had the R-STOL. It's cost prohibited to install an R-STOL system today, even if Sierra would do it. The P models are heavy birds and will work pretty good for 2 adults and gear with long range fuel but for 4 adults the fuel load is going to be compromised.
