You're still in the same price range as a comparably equipped F250...not quite as flashy, but close...and it does have tow mirrors.

Each to his own but I'd buy as much truck as you can afford for a 30' trailer. I went from 27' to 35' TT. I was ecstatic with the F150 when I towed the first trailer. Had many white knuckle tows with the second. The length of the box makes more difference than weight imo. At 30', the OP is right on my bubble but I'd lean to the side of caution. I guess I've given more than $.02...oh well...I'll shut up now. :/
