An attack roll represents your attempt to strike your opponent on your turn in a round. When you make an attack roll, you roll a d20 and add your attack bonus. (Other modifiers may also apply to this roll.) If your result equals or beats the target's Armor Class, you hit and deal damage.
Re: Trailer hitch for under $170 installed! this is a really old thread, but here's 2 helpful fats- 1. the curt hitch has been redesigned so it no longer melts anything. 2. i saw a prius with a uhaul hitch yesterday, and it loked like an 06 prius. #8 Feb 14, 2009.
Some vehicles require extensive labour to install a trailer hitch or wiring. In these cases the price of the hitch and installation will increase. Typically trailer hitch installation on luxury vehicles from brands such as BMW, Audi, Porsche, Mercedez, Lexus, and Volvo will range in price from $399-599.
