Hal,

Your advice is consistently good.

Prevention of blowouts is foremost:

0) Know your tire history.  If the tire has run underinflated or overloaded it may be already damaged.
1) Maintain max. rated tire pressure for max. tire capacity:  50 psi for most.
2) Run as light as possible in the trailer.  Tow dry, and think about every pound you put into the trailer.  If you can carry an weighty article in the vehicle then do it.  Bulky but light stuff is ideal for the trailer, heavier in the vehicle.  I go so far as to carry the spare tire in the tow vehicle which some of you may consider extreme.  But with the propensity for blowouts, some precaution here might be wise.
