In terms of load carrying, there often isn't much difference betwen a warrior and a lightly equiped cherokee 140; for instance, our club warrior was 2325lb mauw, empty 1550lb = 775lb useful load. My old cherokee 2150lb mauw, empty 1400lb = 750lb.
Any way you cut it, it was never more that 3 svelte adults or 2 adults and two kiddies and modest fuel.
An archer II by comparison(Which I happen to have bought by way of an upgrade) is 2550 mauw, 1600lb empty = 950lb load. Still only 2 ordinary adults, two kiddies, luggage and a decent fuel load. Archer III's can come up heavier, so as ever read the w&b.
Curiously, my old 140 loaded with two big blokes in pi and pii and a full fuel load was very close to being out of the w&b envelope, due to forward c of g, whereas the warrior and archer have no such probs.
