I tow a roughly 6000 lb loaded camper with my 2008 4.7 liter tundra. It does just fine. (I wouldn't want to tow much more.) I average around 9 mpg towing. That said your problem is payload. You need to check the yellow sticker inside the drivers door. You have about 1200 lbs payload capacity. And 12 percent of your DRY (No one tows dry) is over 800 lbs of weight. (12 percent is the average Tounge weight transferred to the truck which must be subtracted from available payload.) That means you only have 400 pounds left for people and cargo in the truck, but since you are bound to put more weight in the trailer that number is realistically much smaller.
I think it would tow it, but I'd consider a lighter weight camper if it was up to me. Otherwise be comfortable running in 4th and sometimes 3rd with high rpms. Also, make sure your truck has the factory tow package with the transmission cooler.
As the other poster pointed out high head winds stink. In Casper, WY I think I could have walked faster that I was towing. I got I think 4 mpg on that stretch. That said, 30 mph head wind is no joke and lots of engines would have trouble with it.
