    Posting since I have some things to think about and can't really work on it...

    my 1st gen double cab project, the frame is pretty fucked (rust, abuse, collisions, rolls), so I'm going to make a chassis table and make a DOM frame, I am still looking to Daily the truck when all said and done, I will be continuing to use Raptor 3.1 Live valve shocks with SDI controller, but making a few changes especially to the rear to increase travel from ~14" to ~18" and also looking to make some changes to the front to fit a 37" with tubing only for a 35".

    Traveling a ton for work, but it has allowed me some time to really progress the designs of my suspension/frame.

    To fit bigger tires, I'm thinking I may shift all the front points forward ~2" relative to the Cab, or I'll completely remove the anti-dive geometry (currently reduced to about half OEM) and shift it forward only ~.5" or so.

    I have not wanted to fully commit to a front steer setup just yet, mostly due to the work required to shorten a rack, but I will leave space for it in the future.

    The rear end I'm pretty pleased with my intent, going to a long arm JT geometry (but with a link mounted shock for some motion ratio), and will be pushing the axle back ~1"

    any thoughts?

    besides reminding me that I'm basically wasting a a lot of time and money?

    Unless you’re planning to do a full chassis truck, I would seriously consider building a frame out of 2x3 or 2x4 rectangle. You’re gonna have to get pretty wild for DOM to be substantial enough for strength.

    I was originally thinking 2x3, but I modeled both and the 2 Tube rails were stronger in the FEM I ran, but I have them spaced around 4" on center for most of the run

    But also box fabrication will be so much faster I may just do that.

    Not only faster but far cheaper and likely lighter than a double tube rail as well.

    Boxed rails are way under rated.

    2x3 .12 is around 3.9 lbs per foot vs 2" .12 wall dom is 2.4 lbs per foot, but strength wise can almost gurantee if your stacking the dom with verticals at 4" it will be alot stronger. cool thing with the tube is you can bend them both than tie them togethor vs mitering the rec tube. that and you really wont find a dom rec tube either which definitely adds some strength as well, but yes the rec tube would be faster.

    keeping jersey dirty
    I think for a project round tube is the way to go. Rectangle/square is way more simple and easy for frame rails. Oem's do it for good reason. I find it's more of a pain to build off of besides simple brackets n stuff like that. Adding tube or a complicated mount off of rectangle looks kinda goofy and will usually need some structure or surface area to avoid making a high stress spot or place for a crease to form(dunno the proper terminology for that). With tube you can kinda just notch on another tube equal size or smaller anywhere and it'll be about as strong as it can be; if it isn't add wall thickness or a gusset, simple. That also leaves more free space for parts packaging and bends to pretty things up a bit. Also personally think tube work looks cooler when done up with bends and michell structures n that jazz
    Your idea of doing two parallel tubes sounds rad. With smaller tube trusses in between it'd look so cool. I've thought about that for making the frame of my truck a bit more 3d without committing to a cage

    yeah the OE Frame has sections at 2x3, 2x4 and 2.5x5 with some internal bulkheads (which are what contribute to the rust) as well.

    I also think the tubes will be a little nicer to look at, a bit easier/cleaner to land future-tie in's on as I get to that. Weight and strength wise my calculations show they will be similar with the tube frame being a little stiffer in torsion and the box frame a little stiffer in bending.

    A cage would make both styles quite a bit stiffer in both tests, but like I said, mid-term I want to daily this truck, and the cab is far too small to daily a cage safely without a helmet... I will probably gusset the A-pillar ~edit~ I had more to add here and got distracted and hit post... I have some insights on making the cab stronger/more resistant to intrusion.

    I've designed a pretty basic table, all key feature stanchions, and all alignment stanchions for a rectangular tube frame, and several for a round tube frame

    Planning to order steel today... hopefully back in town this weekend to start working on it.

    My models show ~18in of front travel limited by UBJ at around +3.8" from OE, expecting to limit to ~16" or so, I have not nailed down the spring for this yet, I have a nice 550lb, but calculations show a 400lb spring may be better...The JT rear end will have ~22" of travel on the shock, but I expect to be spring limited to ~18" and I have a progressive rate 125lb spring.

    The current mid travel setup is around 13" in the front and 14" in the rear, one nice thing about building the bare frame is I can still drive the truck while I do all this machining and fabricating!

    A few more JD Fab products added Inner Fender kit and Nylon steering rack bushings. The snorkel is from DRT imported from In House Fab in Australia. Jesse installed the snorkel to account for the snorkel plumbing. A few modifications were needed to lineup with the new opening in the fender and airbox.

    Got some +6 glass from Fiberwerx. Surprisingly it fit up with very little cutting or sanding required. Raptor lined the inside and the outside lip area. Dropping them off tomorrow for a buddy to paint them.

    What application method did you do for the raptor liner? I have a mix and apply kit from em with a spray gun, but I'm debating on rolling it on so it doesn't get everywhere. Plus I have to do it at my parents house. Renting is fun.

    The inside I sprayed with the gun raptor sells, I just made a mini paint booth out of plastic against the garage wall to spray it. The outside lip I rolled on with a 4 inch 1/4 inch nap roller. I did multiple passes rolling it on...probably 6 or 7 passes going back and forth between the 2 fenders.

    Ride height and pre pinion angle measured. Tear down begins. Won't forget to space bedcage up the height of the bed before I cycle everything.

    So my friend wired in my 240v outlet and here's what he did. For some reason I'm feeling ocd about it as I do not want to burn my house down.

    Nema 6-50
    Romex 6/3 with bare ground
    He ran black and red to breaker, then bare ground and white wire to grounded bus bar. He then connected red, black, and white to back of outlet, grounding the bare wire to the box.

    I'm using the left over 15ft of wiring to make extension cord. Do I just use the white wire like a ground as he did?

    I have seen conflicting things about the white wire and some people have it capped off and just use bare wire as the ground.

    I'm sure theres an electrician or two around but i've always used white as neutral on the ground pin on a 50a 3 pin socket, a few welding machines use a 110 circuit thru them so if you were to run true gnd thru the pin you would than be using the bare gnd as a neutral instead of true gnd.
