Total weight IS your only consideration at this point. The smaller a 2 axle trailer you find the lighter weigth rating it will have.
If you are gutting a trailer typlically the weight you put in should not exceed the weight you reinstall. These trailers (and every other brand I know) have an axle capacity to accomodate everything built into them and a small percent greater. So if the trailer has a GVWR of 5000 #'s the axle(s) will be rated just over that and the empty weight of a complete trailer is going to be like 85 to 90 percent of that.
Drag in a heavy commercial cooking gear and you will have issues with a standard set up.
All of the above assumes the axles are in good shape. If you are doing this to a trailer that is older than 20 years, seriously look at axle(s) replacement with a higher weight carrying capacity.
And this is assuming you want to move the trailer to different locations. If it is a stationary project then all of the above becomes just talk. Find acceptable foundation for this application.
