Hey N.Vonstaden, thanks for asking the question here. I would suggest the -47 density. The -54 states for cutaway models only because it’s intended use is commercial applications with constant and heavy duty loads. For an RV application like yours, the -47 will give you enough load support to reduce sway, and absorb road shock and vibration. Hope this helps!
