I've had F250's, F150's and Silverado's. Couldn't be happier with the Jeep Gladiator Mojave I bought last summer. Wish I'd have got something smaller a long time ago. Not as much room but I still get everything in I need.
I have crew cab 1/2 ton 5.5 bed. I get everything I need in there for my hunting trips. I do hunt out a cabin and camps so they may be different from you.
If I had an other foot and half I would find another foot and a half worth of gear to put in there.
If you dont want a trailer just find a foot and a half less stuff to haul along.
Also make sure you are packing things in efficiently. Separate your gear between must have and nice to have and going to use and might use. Make sure you’re not hauling any supplies not in coolers across the country that can be bought were your going after you off load into camp. Just a couple small things open up space.
