Advice for towing a new TT with a 2004 4-door Tundra

I can't emphasize enough that we are very simple people/campers. The kids are getting bigger and need somewhere to sleep. Otherwise, we'd keep our popup. We spend very little time inside when we camp, so there's a lot we don't need/want.

I noticed a couple companies deal with all aluminum TT's that have similar floor plans with the one we wanted. Aside from the high price, what are the cons with these campers?
