Hi,
I've had a couple of utes with canopies for work and I find the best ones to be the Steeltop. In Aussie they are sold as the SAMMITR canopy.
These are a double skin steel canopy so expect them to be heavier than the classic plastic or fibreglass canopy. They are strong, bloody strong! Come in a couple of different options, my one is the SUV type (was new on my old 07 STX, now on my 13 ST).
Main advantages, central locking standard with all models, double skin steel making them strong and not flexing during cornering, padded interior to save damage, tail lift door hangs over the top of the tail gate so it locks this also.
The rear door locks are solid, mine has been opened and shut thousands of times and still works.
After 13 years the springs for the rear door are starting to get a little tired but they are available as a spare part.
All the parts are available including the glass windows (as I discovered a month ago when I broke one).
One last thing, lots of canopies are being broken into to steal tools etc. There is another couple of things that need mentioning.
The side and rear windows are tinted so very hard to see into at night time so harder for the crooks to see if there is anything worth stealing.
Secondly having a steel body means it's harder to get into. Some canopies have thin steel or ali frames around the windows that are easy to flex and gain access, others being either plastic or fibreglass and being cut open with a battery grinder with a saw blade attached. The door/doors and windows are very strong and the steel body means a lot of noise will be generated cutting into it. The lock could be better to guard against picking but most will never try that anyway. They have an internal light with a hidden switch in the door latch so an alarm can be hooked up to this circuit also.
My 2 cents worth.
