There is a lot of good inputs from others and here is my 0.02
I have a very similar setup 2019 crew cab, 4wd short bed, and 5.3 8spd. a 27' camper -> 30' bumper to nose 5750lbs dry. I had to pick it up 2 hours away from home, with only me and my 12yo son in the truck it was a very scary ride home – all back road couldn’t go faster than 50mph (mostly 40-45) on 60-65mph roads. The power was alright definitely can get up to speed.
Consider the following:
Weight distribution hitch: with the weight distribution hitch I can say I am comfortable going 55-60mph on a calm day. Small cars passing me caused the truck to wiggle a bit. Also, truck manufacturer requires you to have a WDH on anything above 5000lbs on ½ ton.
Payload: my truck is rated at 1900lbs with my family of 5 weighing in at 900lbs before breakfast, have about ~900lbs tongue weight (7000lbs loaded * %12.5) so if you do the math we can only pack about 100lbs in the bed – that is not a lot when you are going camping between firewood, food, gas cans, suit cases, and so on. (I would load as much as possible in the trailer).
Lots of pit stops: averaging ~9mpg that is about 200miles between fill up – I take 5gal gas can just in case.
My personal preference I would go smaller if I can, pulling 30+ TT with half ton is a lot of work, the engine can do it, but stability is going to be a challenge.
