Can't help you with suggesting any local CT's for you, but don't forget that you could always buy a trailer without side access and then have it modified to suit.
That's a definite possibility. Tried to buy an MDC today to do exactly that, but apparently they sell enough that they don't need my business. Oh well, I guess that means something better is around the corner.
I'm wondering though how you'd go with security for the guns in that kind of a setup, but you'd know more about what's required there than I would.
Just needs to be a lockable box that's secured to the trailer. I want the side access for easier access so I don't have to lift the bed up and go in over the top. One of the reasons I use the name "Sawed-Off" is I'm a short arse.
I'd love to hear what sort of shooting you do - sounds like a lot of fun.
We do what's called Single Action shooting. Basically, we dress up like cowboys and shoot guns from the old west as fast as we can. It certainly is fun. It's like a big social club with occasional interruptions due to outbreaks of gunfire. You're all welcome to come and check it out. We shoot fortnightly Saturdays behind the Sikh temple at Edmonton. We're there this week from about 1.30pm.
Hope this works. First time I've uploaded something to youtube. This is me on Sunday. We're normally outside doing a few more challenging things, but the torrential rain forced us under cover.
Good luck!

Cheers! This is turning out to be harder than I thought it would be. I never realised I was so fussy about stuff.
