New Travel Trailer

Yeah, go to a few RV shows and look at what floor plans are available. DW & I looked for 2 years for a replacement for the hybrid TT we had. After having the HTT for 8 years we had a list of must haves, nice to have, and don't care if it has it or not.
Do you want a couch or not? A slide? Dinette on a slide, or dinette & couch on the slide? How much storage does it have both inside and outside? Lightweight construction, or stick-and-tin? My wife's biggie - a walk-around bed, not one with the foot right up against a wall. And actually sit on the toilet to see how much room you have, some floorplans are tight on room for your knees. Other floorplans don't leave you much room when standing at the bathroom sink.
Your truck will tow it just fine. What's the payload listed on the yellow door sticker? If you start loading the bed with stuff like firewood, a generator, and other gear you can run out of payload long before you hit the towing limit.
If you've never owned an RV before and want to buy used I'd have another knowledgeable person look it over for possible problems, the biggest being water leaks in the roof. Also consider the age of the tires and if the brakes & wheel bearings have been serviced.

My F-150 EcoBoost is rated at 11,200 pounds towing capacity. Last year I pulled my previous trailer, a 32-foot Bullet, from south Texas to Oregon with no problems. I believe that a 26-29 foot trailer should be well within capacity.

Just a general rule of thumb - the weight sticker on the individual trailer should be at least 2,000 lbs below the max tow capacity of the truck body, engine, rear axle configuration.

Just like your truck, the sticker weight on the trailer is 'off the factory floor'.

Thinks on your truck like a full size spare tire, step rails, dealer added options, etc. - are not included in your truck weight/ payload sticker.

Things on the trailer not included in the sticker weight are a spare tire, battery, propane, any dealer added options, etc. Usually adds 300-500 lbs to the trailer weight.

As Scott suggested

Stay with in your trucks towing capabilities........LINK

I suggest you go to a RV show where you can see lots of different models all at once. It helps to make a list of must-haves like you have already started and maybe find other things to add. For us it was a walk around bed, and plenty of extra carrying capacity (CCC) because some trailers are built in a nearly overloaded condition right from the factory.
