There are light-weight hard-side and specially-designed luxury pop-up campers (specifically made for Tundra pick-ups). I recall a thread a year or 2 ago, with numerous hard-side campers light enough for a Tundra elaborating thereon.

This article is nothing but advertising fluff, rife with superlatives, offering little to
nothing in the way of this truck's ability to haul a truck camper or anything else, let alone a basis to cross-compare, technically, any other similar genre truck. Find another article offering
real technical data on cargo moving capability; the inference in this article is that the Tundra is as capable as a 1 ton or 0.75 ton pick-up (a ludicrous and dangerous assumption!).
