I've got an '02 4 cyl, 4wd Tacoma, and am looking at picking up a travel trailer.
I've found two that are the right size for us.
Got a problem: I don't know how to decipher the different weight ratings.
I have an idea about GVWR - I think it is the total weight of the trailer, loaded, but I'm not sure about that.
Anyhoo, could someone tell me what the max dry weight, or the max GVWR would be for my truck to tow?
Or maybe a web site I could go to to get that info.
Many thanks
