.....14?? my wrecker only has 7 total,,,,where did you get all the extras?.....my GVWR is 33k all considered- but is still plated as a class 6.5 ?....what gives were?....did I get bent over by the manufacture?....OOOoooo do I have a burning feeling!....geofkaye

I'm at home away from my work computer with my drawings, I believe their may be even more crossmembers I know I ordered 22 96" 2x2x.187 today, the rear cross on the back is 2x3x.187 and I'm sure I might have missed one or 2.

The box is 22' long with the 2x2's on 16" centers. that gets me roughly the 14 for the floor, as 2 of them are almost atop each other where the floor drops the 11". The other 6 will go under the frame. 3 in front, under the cab and transmission. The other 3 or 4 will go under the fuel tanks and generator behind the drivers.

In case you are wondering, if I should ever need to drop the trans out the bottom, I will just sawzall the tubes. I think it would be easier to just pull the engine and trans in one shot then split .

after typing this I think you are referring to the The factory cross-members on the truck frame. I had 4 behind the cab but I removed the far back one and replaced it with a heavy steel box to hold my water tank. if you need another factory cross-member, I have one laying on the floor next to my mess. You could use it as a boat anchor.

here is a photo of my truck, notice all the 2x2 notches on my secondary rails

.....THANKS FOR THE INFO....GOT ME WORRIED SOME WHEN I THOUGHT I WAS MISSING A FEW.....course some days I know I'm missing a few of everything....thanks for the side view it explains things to me........cool project for those that like to work their butt off-course in cold weather what else is there to do?....best of luck and shoot a few pix for us now and then as you have time......geofkaye

Awesome! Very professional looking. Coming from a fabrication background I love everything metal and seeing it being transformed like this. Keep the pics coming. Great work!

Blizzard,
What are you using...AutoCad or SolidWorks? I'm trying to get my employer to send me to learn SolidWorks since that's what we use here. I have a copy of AutoCad LT at home but have not messed with it yet. I want to use one of the programs to make some designs for both a stretched HDT and a custom built 5th trailer and see which I like better. I'm leaning towards the 5th as I could unhitch and use the truck for daily driving.

I use AutoCad I have a copy of AutoCad LT 2005 that I bought but cannot get the CD to load on this new computer, so I am using an old (from work) CD of AutoCad 2000 with Mechanical Desktop. but in all the years I spent drawing professionally I only drafted in 2D so I don't use the 3d tools in the Mech desktop.

It is nice to use a platform that your steel fabricator can read so that they can just load your 2d drawing into their CNC plasma or laser and burn the parts out.

Also as far as pictures go, I have quite a few of them posted on a long thread on the escapees MDT site. check them out if you have a minute or 2

Blizzards MDT Conversion Plans

ps when you are working with steel, the area command in AutoCad helps figure out the weight of each part. I am finding that a steel weight chart is very handy, one it helps me keep the truck balanced front/rear axle and 2 figure 3 dollars a pound for steel that requires any cutting and forming. a simple piece of 3/8 plate gets expensive quick!

wow, I cannot believe that I have been registered on his forum for an entire year already, a lot has happened in that year, We found a truck, sold our Roadtrek, and started on the conversion.

This week was a new turn, after having our truck at a local trailer repair shop, we have pulled it and moved it to C & S Conversions in Watertown SD. It is with a bit of irony that Chuck at C&S is a high school friend of my wifes. I wish now I'd consulted with him from the very beginning, I think I would have saved thousands of dollars in metal fab and mistakes.

Check out my story line on the Escapees forum, I posted current pictures, and to post on both forums is redundant, but I much prefer the build it vs buy it attitude here.

....I DON'T REALLY WANT TO GIVE ANY THING AWAY....BUT....if you have worked on any of the toters or MH's[TruckConversions] you will come to the conclusion that my crew did[and i didn't] and that is to build the inside after the structural steel is in place and then the plumbing and wiring insulation and then the outer skin.....just a little hint here-you might ignore it or consider it when building one yourself.....but we are tired of taking apart the inside many many times to get things to work well together or make those frustrating changes.....like changing a 15 amp wire[14ga] to a 20 amp wire[12 ga.] and such mundane things like that....windows are last btw......geofkaye

That is a very good point. geofkaye, when you have been there, planing ahead pays off. I put the back of my box in last, just for that reason. blizzardND. Nice jub you done, hope your builder stays with your project and parks his rase cars. This is race season , sometimes it's hard to stay away from the track, when you are headed to Knoxville, IO Good luck. Roadside
