First of all, you can't use the truck model (F150 or 1500) as shorthand for it's capability. Individual trucks can vary widely in their capacity ratings, so you need to get the specs for the specific truck you have or intend to buy. For a given trailer, the truck needs to have enough GVWR, Payload, GCWR (tow capacity), and hitch capacity (tongue weight and pulling) for it. Others have already noted most of these in their replies, but you need to put it all together to make sure all the boxes get checked OK.
The truck manufacturers tow ratings are not specific to RV trailers and other types of trailers have different characteristics that place different loads on the truck. Generally speaking, a truck can tow a heavier utility trailer or low-boy car hauler than it can a travel trailer or fifth wheel RV trailer. Any of those trucks can easily pull the weight of that 8746 lb GVWR trailer, but there's more to it than that. The tongue weight (load placed on the truck suspension and hitch) will be 10%-12% of the trailer GVWR, or 875-1050 lb. You need to look at the truck payload (cargo) rating to make sure it can handle that and still have leftover capacity for driver & passenger and any gear you carry in the truck (including the trailer hitch itself). You also need to make sure the receiver hitch itself is rated to handle the pull (8746) and the tongue weight (875-1050). It may need a weight-distributing (WD) hitch for the latter. Also, if it turns out you are near the cargo payload limits, verify that the rear axle weight rating (GAWR) isn't exceeded. The cargo payload isn't always evenly split between front & rear axles. Especially if the truck is equipped with passenger-style tires (as many 1500 class trucks are these days).
Having said all that, a typical half ton (1500 class) truck can handle travel trailers up to around 7500 lbs. They can be configured with options to reach 9000 lbs or more, but you may have to special order to find one like that. Smaller engines, e.g. a V6, have to rev up a lot to produce that necessary horsepower because they lack low-rpm torque. That means slower acceleration & hill climbing, and usually more noise in the truck cab. It does the job, but you will probably be happier with the bigger 6.2L V8 engine. However, there is probably some modest MPG penalty for having the extra pull-power readily available.
