Equipment in concession trailers

For those with concession trailers, how have you successfully anchored your equipment? I bought some small D rings at Lowe's but I don't think they will be able to hold my larger equipment. I don't feel comfortable bolting these only thru the floor and the floor joists aren't large enough to completely anchor all four holes of the larger D rings. Any ideas?

I have a smoker about 4' wide by 2' depth and 6' tall. Probably 200-300 lbs? I also have a banquet caterer thats about the same size. Probably 200lbs?

Thanks guys, that's what I'm looking for and hadn't thought of. I think I'll do the track system and some floor mounted D rings for extra strength.

HBMTN - I can imagine what that looks like! My fear is the smoker breaking loose and destroying the trailer and everything in it.



One more question if ya'll don't mind.. I have a hood and vent in my trailer and I plan on mounting my smoker underneath it. I'm thinking about enclosing this area with plexi-glass. That'll let my customers see the cooker and stop the fan from sucking all my ac out. I should have about one foot of distance from the smoker to the plexi on all sides. Anyone ever try this or have any input?

Also, where'd you buy the wall track? I don't see it at Lowe's or Home Depot.
