Toyota Highlander V6 pulling 3500# Casita??
Anybody doing this? Their V6 is rated for 5000# or is that only with the tow package? Can any older V6 Highlander be retrofitted with the tow package if it didn't come with that originally? ...

Highlander tow prep package:
According to Toyota, the XLE and above have a heavy-duty radiator and an engine oil cooler. They also have a 200W fan coupling (i.e., powerful cooling fans), a supplemental transmission cooler, and a 150A alternator.
Looks like the tow package does have some substantial differences. Starting with 2016 models the tow package is standard on all V6 models.
