Of all the information you provided none of it is useful at all in determining tow capacity. The only way to find that number is too look it up in the guide 2oldman posted for you.
After you find the number you have to realize that it's not that simple. There are many different kinds of trailer. Among them all I think that a hard sided RV is the most difficult to tow. It has a very high frontal area for wind resistance, a very large side area to induce sway, a high percentage of tongue weight, and very little ability to move weight around to change the tongue weight.
A truck that can easily handle a boat or flatbed trailer of 8,000 pounds may struggle mightily with an RV of only 6,000 pounds.
Another number you need, which you didn't provide, is payload. This is probably the most important number, particularly for a class 1 truck like yours, in determining how large an RV you can tow. After putting people and gear in the truck and accounting for the weight of a WDH you will likely find that you don't have enough payload left to account for the tongue weight of an RV that weighs near your published towing capacity. The only way most class 1 trucks can tow at their published number is with an empty truck bed, no passengers, and with a trailer like a boat trailer that has a rather small percentage of tongue weight.
