I will admit that I used JR Consumer as part of my 5th wheel buying decision. It helped me focus a little more objectively on the higher rated brands and differentiate between the various levels (entry, middle, high, luxury....or something like that) of 5th wheels. Once we identified a specific brand and model that we were interested in, I ran one for that model.
While there is much wisdom to be gleaned from the internet it becomes a little too opinionated and subjective for me to filter through.
