While there is no visual guide available to determine the sizing for the MORryde sliding cargo trays like the # MR38FR, it really depends on the height, length, and depth of your RV compartments opening. The # MR38FR that you were looking at, for example, measures 90" long x 36" wide x 6-5/8" tall with the side mounting tracks included. With this specific tray, your compartment needs to have these minimum dimensions to install. It is also important to factor in the height of your cargo that you wish to store on the trays to make sure you have enough height. This model is a 2-way slide that slides out and in.
If you make your depth, height, and width measurements and determine that you need something a bit smaller, I recommend using the MORryde # MR77FR. Like the # MR38FR, this slide is a 2-way slide. Although, it has the advantage of extending 80% compared to the 60% extension length of the # MR38FR. With this factor, you will have more ease of loading without having to bend inside the compartment to place cargo. The # MR77FR measures 72" long x 26" wide x 6-5/8" tall with the side mounting tracks included in the measurement.
It is important to note that if you have a lip at the edge of your compartment, you need to use the height adjustment kit # MR34VR to raise the tray over the lip for the tray to extend and retract. The kit raises the tray 2-1/2", 2-3/4", or 3-1/8" higher to go over the lip.
