Frame is the same width on your truck. Whats the GVW of your trailer? You need a hitch that exceeds that! Personally I would have one built like a medium / heavy truck has. For a 1 ton ,flat 3/8" or 1/2" plate with a Reese receiver through it, Brace off the back of that back into the frame, angle gussets at both ends, and some D rings for the chains.
