that is quite unfortunate... LOL.All my seats, except the front two, are already removed.
every pound makes a difference. but also car maintenance, and tires. I have seen 1-2 MPG difference with chevron techron fuel additive. it all makes a difference.Well the seats are probably 150 lbs. Currently I may have like less than 50 pounds of stuff. I'm not too concerned about MPG. It's going to go down when I build my campervan, between stuff on the roof adding air drag and hundreds of pounds of extra weight.
