I dunno...I buy a LOT of gas. My Winnebago gets about 7.5mpg. I calculate it's fifty cents a mile just for fuel. So a 1200 mile trip costs at least $600 for gas. OUCH! Taking the bike on the same trip costs about $100. But then I can't take my wife and three dogs, or my teenager if he decides to join us. I have also estimated the cost of owning the RV is about $12,000 a year. I guess we all have differing priorities. I have four other cars and the 3 bikes. Seems like I spend my money 'real good'.
