I highly recommend a long bed truck. It will give you probably 4 times more choices of campers. Also, if you want an inexpensive truck, most of the no frills work truck type trucks are long beds because that's what people who actually use trucks for truck things want. I too would also recommend a used camper unless you have plenty of money to pay cash for a new one. When I sold my 2003 camper in 2018 it went for under $10,000. This was an 11' model with a dry back, generator, remote jacks, 2 awnings, solar panel, etc.
Campers are heavy. A 3500 SRW is a minimum. If you intend to have a 4wd diesel crew cab truck with lots of options, haul lots of gear, and have a nice big camper you really should be looking for a dually.
