Here in Reagan country (you know, the good old USofA, 'Murica)
almost nobody tows anything behind anything but a mighty great
gas-hog.

Even the Ford F150 pickup-truck is regarded as a marginal tow
vehicle--- things like my Toyota FJ Cruiser with it's mere 4.0
litres are considered pikers.

An F150 Super-Duty or an F250 or a Ford Expedition or Excursion
are more the norm for pulling...certainly NOT a Volvo passenger
vehicle!

It wasn't always that way. Back in the 1960's you'd routinely
see a Buick or Ford station wagon (that's an Estate to those of
you across the pond) albeit with a 360 or 427, pulling a travel
trailer (caravan) with it's ass hanging low and the lot swaying
about. (Before the 'Lucy' show, she and Desi Arnaz did a great
movie called 'The Long, Long Trailer,' which didn't much
exaggerate.)

But mostly, over here, the travel trailer has given way to dedicated
'motor homes' which are built on commercial truck chassis. The
very smallest of these are built on delivery van chassis, but none
has less than 200bhp these days. Back in the 1970's and 80's they
built some on Toyota light truck chassis, with as little as 2.4L
to propel them forward, or hold them back. They've gone the way of
the dinosaur.

Just to put it in perspective, on my FJ Cruiser, I'd not tow
anything greater than one of the tiny fiberglass 'micro' caravans
or a tent-trailer. The speeds are too much, the mountains too
high, and the distances to great to consider otherwise.

Glad you're okay.

A mere investment in a 12 miles-per(US)-gallon vehicle will make
your life easy--- should you come into the fortune to feed it!
