I am about to purchase a new travel trailer and I am trying to compare vehicle specs over the internet. I have used several comparison charts and why am I not surprised that I get different specs from the various charts when comparing the same vehicles. I am confused though by two of the ratings listed in these charts. They list a "Standard towing" spec, and a "Max towing". Can someone offer me the explanation of these ratings? One chart says that my vehicle has a higher "Max towing" rating then the compared vehicle. Yet the "Standard towing" rating is lower. This does not make sense to me.
