The things I pay attention to are the engine power (rarely a limiting
factor), transmission (if a tow package isn't fitted, expect to change
fluid at least twice as often as recommended; you don't want that fluid to
turn black), brakes (trailer brakes must be kept in excellent condition)
and stated tow limits including the tongue weight limitation and the gross
combined vehicle weight rating.  Remember the up/down, left/right and
fore/aft forces on your hitch are working the mounting points on your tow
vehicle, so towing with a 1/2 ton might mean you have to keep an eagle eye
on loading.  If you use a huge offset on your hitch (I've seen plenty of
lifted trucks using at least a 10" drop) you are significantly increasing
the torque effect of that long arm to the loading on the frame.

The 2007 Toyota Tundra I sold last year was rated at 10,600 towing capacity
and 1060 lb tongue weight (with a load distributing hitch; without one it
drops to 5000/500).  I could see that the frame rails where the hitch
attaches are very thick.  Empty weight on the truck is over 5250 lbs lbs
when completely empty and the GVWR is 6900 so to pull that load the truck
itself must be kept very lightly loaded.  Fuel fuel is 156 lbs.  Add a 180
lb driver and a few travel extras and that leaves a margin of 1300-ish lbs
for tongue weight.

One wants to be pretty accurate with the tongue weight when towing at
the GCVWR (I couldn't find this figure for the Tundra but assume it has to
be well over 15850, otherwise, assuming the trailer weight is 10,600, there
is zero capacity left for driver, fuel, etc.).  How many of us weigh our
total rig, the trailer weight, and just as important, the tongue weight?  I
tried one of those hitch balls with an integral weight scale but it was
junk.  Thankfully the local cotton gin charges very little to weigh
vehicles.  There are some salvage yards not far away from my home that also
will let me use their weighbridge but they always seem a lot busier than
the cotton gin.  You can use the trailer jack to put the hitch at the same
height used while towing if you're going to weigh the trailer tongue
separately.

These days we tow with a 170" WB Sprinter Roadtrek camper van with a
standard body and the 3.0 turbodiesel.  It's rated at 7000/700 lbs. but I
keep that to 6800 max when not traveling solo; however my typical weight
with a race car in the 18' enclosed box trailer is less than 6000.  No
problems so far, but I do change the transmission oil early and I keep an
eye on transmission fluid temperature (using a ScanGauge II that plugs into
the OBD-II terminal) when towing in the mountains.

By the way, I love my little Bluetooth camera on the back of the trailer.
Signal is strong enough and monitor image is fine.  I feel more confident
when returning to the right lane after passing.  The one I bought doesn't
seem to be offered any more but this model is what shows up when I look for
my previous Amazon order:
