Looks like GVW of 7620# (one just under a 27' 5er ) is quite light. Don't see why your truck shouldn't be able to tow it. Figure a pin weight of 1500# or so that you would possibly put on the hitch in the bed of your truck...I'd weigh the truck and see what weight is on the drive axle and subtract that from your truck RAWR, (will be listed on drivers side door or door jamb. The difference will be how much pin weight you can put in the bed of your truck without going over your trucks rear axle weight rating.
Also, if you have "P" rated tires, you will probably want to go to an "E" rated tire...
Not that familiar with specs on the 1/2 tons, but seems like a fairly light weight 5er to me.
