As long as there is enough space for the rail with the Velcro you should be good to go.

 

I also bought the TonnoPro Tri-Fold. Got it on e-Bay from a dealer for $232. It works for me and is very easy to remove and re-install. Has never leaked or caused me any problems. I highly recommend it if you are just looking for something to keep the bed dry and things out of sight.

 

I did see a video somewhere about the savings in gas with the cover. The engineer from Ford said they design the truck with aerodynamics as to where they will not help any. That is the reason the tailgate is kinda large a fat on the top, so the air from the top of the truck hits that and keeps the air moving in a good smooth direction. Although I could see it helping on a long bed like yours, he was just showing the video of the air on a CC short bed.

I do have one also, I got the tri-fold from Xtang, lifetime warranty and very easy to install and very light.

 

I've never seen a savings with a lid and I have had them on three different pick ups.

 

Funny cause its ina the owner manual that says it will improve fuel economy. And it probably does but not enough for most to notice considering all the other variables

 

it's all in the fine print baby...

I used the Access Roll-Up Cover on my 2008 Dodge 3500 Long Bed. I saw 1.5 - 2.0 mpg improvement at highway speeds.

I just got another one for the F-350. I don't have any data yet.

I was very much pleased with the last one over a two plus year period.

 

This is what I have on my past 3 trucks:
Pace-Edwards, maker of hard, retractable truck bed covers and tonneau covers
Very durable, but I dont know if it would work with Tuxedos weatherguard chest.
Never noticed a difference in fuel mileage.

 

Mostly they keep your shtuff your's and by not getting ripped off all the time, you have all this extra money to buy fuel which makes you feel like you are getting more milage and bang for your buck.

 

I just put a Bakflip F1 on mine last week. It looks and works great. I bought it through Amazon for $809.36 with no tax and free shipping. I would buy it again. The F1 is the top of the line model they offer. It can support 600#'s evenly distributed.

 

ok so what cover would you all chose if you had a weatherguard "flush" bed box

 

I use a Diamondback HD cover. Installs and un installs in 10 minutes but I can put 1,000 lbs on it and you can buy it linex'd, and I know how you love your linex.....They are made in PA just a bit west of you. Here are some pics.

 

very interesting. im intrigued

 

Not cheap, but no one is getting into it with 2 locks, it is diamond plate aluminum. pretty much water proof, as much as any of em. Wont collapse with the weight of the snow.
