Went to quote a job today for a guy to build a garage for a RV. The building is 14ft wide by 30ft long with 14ft walls and a 4/12 stick built roof, with shingles. This guy has no plans and does`t know anything about building.He tells me he wants to have it built with no ceiling joist because he is trying to save money and he isnt going to be putting a ceiling in anyway.[RE. very cheap!!!] I tell him it will have to have joist to keep the walls from spreading out. My question is what would be the least I should figure for my rafter, joist combo. As it is now, I have it figured for 2 x 6 rafters and 2 x 8 ceiling joist, 16 on ctr. Is this overkill? There is basically no snow load here,as we are located south of Atlanta Ga. There will be RO for a garage door that will be 11ft x 12ft ,so the door guys will be needing something to hang the door from. Normally I try to steer clear of customers like this, but this guy could potentially open doors for me in an area that I have been trying to get into for a while. By the way, I have a call in to the truss company for a quote. It does have to pass inspection!

Trusses are a great option here, though probably more than the client wants to spend, 2x6 rafters and 2x8 rafters is how I would do it, but 2x6 cieling joists would be acceptable, if it's spongy, you can strong back it over the top
also, building code usually calls for a sheetrock ceiling for firecode
There needs to be a fire barrier between garage and living space, but this is a separate building

Thanks guys. Interestingly enough, truss co. calls me back today and their quote was $140.00 more than I can buy the materials for to stick build.
And you were going to frame the roof for $139? (:-)
2x6 is fine for all of it.
if the joists are only there to act as spreaders/rafterties, 2x4 would be fine, but eventually somebody will put something up there, so I would use 2x6.
I would refuse to buildd it without the ties. A structural ridge beam that long would cost him a pile of money
