I really like the 7.3 godzilla engine from ford. Basically, I don't envision us towing super frequently plus living in a city, it would take a substantial amount of time for the extra cost of the 6.7 diesel to be worth it. Plus in california, diesel is super expensive right now. The primary goal of the truck would be to get off the beaten path as much as possible, thinking trips to baja, blm camping etc. With that in mind an f-250/f-350 tremor is probably the sweet spot. F-150 will get better gas mileage, be more comfortable since its not a solid axle but will also be limited by its payload so it would rule out a slide in camper which may or may not be in the cards.
