Yeah, each setup has its own advantages and disadvantages. The popup camper was actually a really comfortable living space for us, which, as full-time travelers, was a huge plus. We definitely enjoyed the ability to cook inside our living space last year, especially up in the mountains in heavy rain or snow (or mosquitos in Alaska). If the weather was bad, we could set up quickly, get inside and be completely comfortable. Now, we don't have that luxury, but we haven't really needed it so far this year. We've spent the past 2 months in Baja, so cooking outside isn't a disadvantage at all. We're planning on crossing over to mainland Mexico and continuing south though, so we'll see how that changes going into the rainy season. We do have the annex for the RTT, which would give us a more protected space if needed.
We did lose a bit of space for carrying gear, and fuel efficiency is a little worse, but overall the smaller size of the Land Cruiser is a huge plus. It's way easier to navigate tiny roads in small towns, find parking, etc. Plus the LC is more capable off road than the big f250, and the rig is much lighter (it'll be easier/cheaper to get on ferries or stuff into a shipping container if needed). And actually a big reason we switched was looking further into the future. We're not going to be traveling full-time forever, so the LC makes way more sense as a daily driver than a 3/4 ton truck, and it'll be much easier to store a RTT than a camper.
