I am 'newer' to the towing world and hope those who are pros can give me a few tips. Right now, I have a 2013 Ram 1500 w/ Class IV Hitch, Airbags and 3.92 gears. According to RAMs website my truck is rated at around 11,000lbs when properly equipped. I also have a 10K rated WDH so I'm assuming with all of this I should be rated at 10K from the bumper - is this right? I currently have a 4,800lb Aerolite and I'm looking to get a larger Dutchman that is around 37' and has a dry weight of around 8,500 lbs. Hopefully I don't need a new truck to get the job done! Thoughts?
