We have the 36FL with the washer/dryer and have been full time for a year. We have all the storage we need for clothing with some room to spare. I even have a suit hanging in the closet for special nights out. Most of our clothing is for temperatures above 70 degrees but we both have clothing for cooler days. I keep my suit, a few pairs of slacks, shirts and shoes in the closet. In the armoire drawers I have jeans, shorts, undies, socks and PJs. The drawer under the bed is for cool weather clothes. Sweaters, sweat-shirts and such. I don't even use the storage over the bed. We also have two plastic containers with some dive gear stored above the washer/dryer.
I think it's a matter of packing what you actually need and not what you think you need. The old vacation adage of "bring half the clothes and twice the money you think you'll need" holds true for full timing as well.
If you like the floor plan of the 36FL but are worried about storage.... don't be.
