Don't see too many of them here. Just the same height as the cab. Windows, lockable lift up back.

Don't see any box trailers here too? Would have thought invaluable here?

carryboy, aeroflex, top up

trailors are a bit more difficult - carry boy do some and there are some other companies, but the law requires registration, i believe.

Don't think much on Carryboy, just to many problems + cost around 32 - 33,000 baht. biggest problem I found with them + other friends carryboys have the same problem, No frame for back window, handle breaks, [security not good] the lift struts appear to last no time at all, as Fiberglass the paint fades........... My truck and those of my friends are all in the same business and the canopy is opened many times a day [maybe fine for private use opened a couple of time a week]

Now on my 2nd truck with the steel canopy from http://www.sammitr.com/en/products/products.aspx

price 28 - 31,000 baht depends on which model/type you go for..

This is my opinion only as have had both types fitted to all my new trucks..

Thanks mate. I'll have a look
