Air Shocks?

I have a 1996 jimmy 4dr 4wd (http://www.automotiveforums.com/vbulletin/#) and am going to replace all four shocks and saw some monroe air shocks for the rear, i tow a small trailer here and there would it be worth it to get them or just some regular ones? I was also looking at the reflex's for the front and suggestions thanks

Air shocks can be a pain on air lines and readjusting for a load.
I would go a good quality regular shocks or gas frilled sentra track monroe type shocks.
For the extra weight on rear a good adjustable overlad spring works good.
