3 major considerations...
1. What is the capacity of YOUR TRUCK. That can be found on a yellow sticker on the door post. Now, take that and deduct everything you put in the truck, both interior and the bed. That's you, spouse, kids, dogs, aftermarket accessories, tools, firewood, cell phones, tablets, hitch, etc.
2. The trailer dry weight and tongue weight is only useful to the driver that delivers it from the factory. Once you add the battery, fill the propane tanks, and fill the camper with bedding, food, cloths, water, drinks, pots, pans, coffee maker, kids toys, etc. the weight will increase rapidly. I'd hazard a guess that the tongue wt. will climb to nearly a 1,000 lbs before you know it.
3. Consider the sail area of the trailer. As I see it a 30' camper can create a handful to control on a windy day or with passing large trucks or busses. This will spark many debates as many folks towing with a 1/2 ton will say it's fine. Others, such as myself who have towed long trailers with both 1/2 and 3/4 or larger trucks will say you need a larger truck.
At the very least, take the length of the trailer into consideration when choosing a hitch. Don't skimp and get a hitch without sway control and don't consider the friction sway control that's a flat bar connected to hitch and trailer that you have to remove to back up. Do a search on the forum and you will find many posts on the subject.
Welcome and hope you find what you are looking for. Many good, knowledgeable folks here that can help you along!
