Life and my business have been so full speed I haven't had any free time to work on the front mods, or anything else for that matter.

I'm happy to say the all the mods have held up 100%, except I have 'modified' the monocoat on the two lower corners of the boat tail off roading in the desert. Monocoat doesn't stand up well to cactus. Ha. Interestingly enough, we haven't torn off any coroplast on the belly pans, even though I've scraped it a time or two.

The extended hitch has performed flawlessly so far also. Every time I've taken the RV out since the last entry it has had the quad and trailer hooked up so I haven't done any more mileage runs either. I did drive it to an RV show in Phoenix back in March, with no trailer for once. I was doing 65-70 the entire trip because my sales rep that I was following has a lead foot, there was a crazy crosswind/left front quarter headwind, all the way up, and it still got 15.45mpg on the way up, and 16.9 on the way back. The winds were so crazy I don't put much faith in the return number though.

I'm not wishing for it, but at some point business will slow down and I'll get to finish the front mods and the wheel fairings. I've got the raw materials, just have to find the time to do it. Now that I'm thinking about it, I did manage to weld together some frames for the dually wheel fairings. Everyone keeps telling me they are a waste of time but I'm stubborn enough to try it anyway.

It never fails, every time I have a day coming up where I think, yeah, I can work on the RV, something happens with her family, or my family, or one of my customers calls with a - gotta have it yesterday order. Anyway, it'll happen.

My notes from Mythbusters haven't survived,but I seem to remember that during the F-150 Tailgate testing that the pickups returned on the order of 16 mpg at around 55 mph?
For your rig to be generating these kinds of mpg numbers at 65 mph is really inspiring.
And Edison was probably quite literal when he talked about 99% perspiration!
