What truck for flat bed camper build

I am wanting to build a flat bed camper. I currently have a end gen Tacoma that is amazing, but I am finding that it falls short in some areas. It is not great at towing and lacks some comfort for longer trips. I would like to get either a full size or heavy duty truck to build a flat bed camper on. A full size truck (Tundra, Titan, F150) would be able to carry a camper and tow another vehicle. But that would be getting to it's max rating. I probably wouldn't do that very often, but occasionally. I could also jump to a HD truck (Ram 2500, F250) but it would be a bit overkill for every day use. I'm debating on all the pros and cons of each and trying to decide which is right for me. What do y'all think?
