So, I got an average of 20L/100kms this weekend pulling the trailer up to Grand Beach. 22L/100km on the way there, at about 110km/hr, and then 18L/100km on the way back, at about 100km/hr.

For reference, pulling the same trailer, with bikes on the roof of the van, I would get about 14L/100km. So, the truck is definitely worse.
BUT, (and this is huge) with the van, you definitely knew you were pulling a trailer. The trailer felt heavy behind the van, and the van would get pushed around a lot by the trailer. Performance felt sluggish, and forget about passing maneuvers. It was tiring to drive. The trailer was just tall enough that I couldn't see over top of it with the van's rearview mirror.
In contrast, the Tundra is so big and powerful, that at times I forgot I was towing. The effect of the trailer on the truck is negligible. The trailer doesn't push the truck around at all, and while an extra 2500lbs does certainly impact performance, the big V8 still had PLENTY of reserve power, and never once felt strained (which makes sense, considering the trailer isn't pushing the truck's capabilities at all). Plus, I could see over top of the back of the trailer, and use my rearview mirror without any problems.
So, yes, I burned more gas towing with the truck that I would with the van, but the experience in the truck was so much better. I could definitely do a 13-14hr drive in the truck pulling the trailer, while in the van, I was done after about 8hrs of driving...it was just that much more tiring.
