way too much trailer for a 1/2 ton SUV, even an extended one.
an Excursion or 2500 Suburban would be the only SUVs for that big of a trailer.
i wouldn't tow that big of a trailer with my family in a Expy or a Navigator.
i totally agree with your father in law and brother in law.
it's only a matter of time and luck before your Navigator gets overwhelmed.
