We had a Dutchman 27' Bunkhouse that weighed in around 6700 pounds. I pulled it with both of my 3/4 ton trucks one with a V10 the other a Hemi. No problem pulling it, but I was glad I had 3/4 ton when it came time for a panic stop. I'm not real sure I would want to pull it with a half ton (more specifically try and stop it), if'n you had to stop quick that 1/2 ton might get squirrelly on you.
They do make shorter 5th wheels that may work for you though.
