I did haul quite a bit in my life and weight is not affecting mpg while on highway driving.
I had 10,000 lb forklift on my 10,000 flatbed and could not record mpg change.
Fact is that with heavy load you drive more carefully, meaning slower and that might offset higher consumption.
12mpg is what would make owner of pickups with V10 happy, but pickups are driven 70-80 mph, while 55 mph sure can save lot of gas.
Same happen with motorhomes pulling a toad. Owners report no change in mpg, what I believe is due to slower driving.
So don't worry about corians. They are not that heavy to start with.
I put about 500lb of granite in my vintage conversion and am not worry about it.
Love the convenience of cleaning the floors.
Our experiences have been quite different. When I pull an end loader in a 10,000 lb. trailer behind my Ford truck there is certainly a difference in mileage. When driving solo I average 17.5 mpg with city and highway driving. When pulling the trailer/loader combination it's 90+% highway driving (at the same speeds as when solo) and the best I can do is 14 mpg.
We have a similar situation with our motorhome and Jeep. When driving solo the motorhome averages 8.3 mpg. When pulling the Jeep it's 7.8. Granted it's only .5 mpg difference, but there is definately a difference.
