My setup is heavier than yours, but I had the same dilemma. Could I hook a bigger trailer to my existing truck, and "make it work". I can tell you from personal experience that you should think carefully if you are wanting to upgrade your trailer. I have a 2000 F350 SWR 7.3 diesel, and we upgraded our trailer to a 16k Voltage 3905. I read the specs, and talked to "people who should know about these things" and decided that with a few upgrades, my well maintained, low milage truck should do the job. I am only slightly embarrassed to tell you that I learned a very important lesson, and we now own a 2010 F450 dually. The F350 is for sale. You can read my post on one of the other threads about my experience, but you should know that if you have questions about your setup, you are worried that it won't be enough. If you are worried about it, you won't be comfortable driving it and will not enjoy camping as much, and will probably not go as much as you would like to.
