IMO keep the gvw of the new toy hauler the equivalent of what you have now. The toy hauler will hopefully (should) have the payload to take on the golf cart (hopefully). You'll be skating a fine line if you're not careful so get some scale readings empty, loaded without toys and with toys to see where you are and adjust accordingly. You've got all the numbers so be diligent in what you purchase....I doubt you want to be looking at a new truck too....
