Towing w/ Honda Odyssey
Don't have a clue, but your owner's manual might, or the dealer.
If you don't have a transmission cooler in the vehicle, it is better not to tow anything.
There are several values you need to know. First is the GVWR (maximum weight) of the trailer. Then the 'pin weight', which is how much weight the trailer loads onto the tow vehicle. As for the Honda, you need the GVWR (maximum weight), GCWR (maximum weight of truck and trailer), GAWR (maximum weight on each axel), Cargo weight (how much stuff and people will be in the Honda) and for the hitch, maximum weight and tounge weight.
If adding the trailer will exceed any of these limits, avoid that trailer. It is even more wise to have a safety margin below these limits.
