First, the 3000 series Bigfoot
trailers ar NOT molded fiberglass
; they're bonded panels assembled in a more conventional fashion, so we don't discuss them much here.
As a Bigfoot
25RQ owner, I'll tell you that the 3000 series are HEAVY. MUCH heavier than my 25RQ. And I do tow my 25RQ with an '02 Tundra occasionally.
You don't say which Tundra you're considering. None but the latest oversize Tundra would be appropriate for the 3000 series trailers, and even then, the 3000 series is in the realm of the 3/4 ton and 1 ton trucks. While the 28' 3000 has an unladen tongue weight
of 875 lbs, well within the Class III spec for hitches, the reality is that the loaded trailer will be pushing a thousand pounds necessitating a Class IV receiver on the truck (1,200 lb max tongue weight
, 12,000 lb tow capacity). I'm not sure what the new Tundras come with equipped, but I doubt it'd be a Class IV. I'm not sure I'd want to try that with any 1/2 ton rated truck, regardless of what the "tow capacity" is as advertised. That's clearly heavier truck territory.
