I have an 06 double cab long bed trd sport. I was kind of sketchy about owning a truck with a plastic bed and before I bought it I did not hear any bad news about them and this still hold true today. However, today I was walking in the bed of my truck when it was empty and I stepped next to the wheelwell on the driver side and heard a crack. I looked and did not see any cracks, so i walked around in that area a little more and jumped lightly on it and heard a crack one more time but that was it after jumping on it for another 5 min after. Yeah, some might say well if you heard a crack why jump more, but I have not carried a heavy load yet and I am going to vacation camping in month and I want to make sure that I do not have any problems at that point. Has anyone heard of a bed cracking or breaking on an 06 long bed????? I think it was motor trend who wrote a review on the truck and said that they drove it from Alaska to CA, and at one point the metal toolbox that was in that back got loose and started banging around but no damage was done to the bed. Sounds good but I am still a little concerned since it is plastic.
