what popup trailer do you have / looking at getting
Don't have one yet, but I'm cheap so I'm guessing an ultralight might be out of the question. I just don't want to be limited either - just in case.
Whatever your thoughts on the tow ratings with vs without the tow package, just keep in mind that if you don't have the tow package your only rated to tow a max of 1500lbs. If you were to get into an accident while exceeding that weight your insurance company will most likely drop you on the spot and leave you on the hook for whatever damages may have occurred. That risk seems much more costly than the cost of the tow package.
Now why did you have to go and ruin all the fun? lol Yes, this, among others, is another reason for concern.
I just did a cursory look through the Pacifica and Odyssey owners manuals regarding towing. It's clear as day in the Pacifica manual that the limit is 1500lbs trailer weight and 150lbs (149lbs) tongue weight "without towing package." My guess is it can support more tongue weight but 150lbs is 10% of the claimed 1500lb max tow capacity. I wonder if you could make a case if you did the necessary upgrades yourself that it met the same criteria. Couldn't do sway control, but everything else. Don't want to test that though. It also suggests that in order to maintain the warranty, all these "guidelines" need to be kept. What's interesting is the GCWR is 6500lbs without tow package and 8600 with.
The odyssey is more vague, and makes no distinction between towing package or not. It has a maximum trailer weight based on number of occupants, and a maximum gross vehicle weight. That's it.
So, it still leaves me with the question... why?
edit: looking closer, the chart with tow limits actually says they're for the given drivetrain. Change the drivetrain and it doesn't apply? So, throw in the bigger cooler and you're good? (probably not, but bureaucracy stinks)
