I have a wind deflector for sale forthe roof of your truck togive better MPG with 5ER { about 3 to 4 1/2 }that I used when I pulled the last few TT that were flat on the front cap { Roamer }. Now that we have the new CT29RLX with the verry SLIPPERY front cap I get the same 13 to 14 avg. MPG without the wind deflector &this is in goog shape $ 150 + s&h or if your going to the TX. rally I could bring it with us. Tim
