true. In my case just to prove my Bride wrong.
well here is one update.
Dom tube starts as Hrew tube with a slightly thicker wall then it is drawn over a mandrel ( forming die) to flatten the weld seam and reach the final dimensions.
It's not cored solid tubing

Also I'm way digging on the trailer build.
Just watched your videos on youtube. Got to say I like what you've done so far. I'd like to see what you did to mount your Tuffy console. I've got one to install, but it didn't have the stock brackets for mounting. I'd like to see how others have done it for some thought starters..
Good work.
Good work.
Thanks guys. I got the IM notices but only am allowed five!!?? Will empty out my inbox
Your videos are entertaining and have a high level of production. Overall, I like them a lot but . . . I don't like misinformation.
After watching your video on trailer material pickup it is apparent that you either don't understand how DOM tube is actually made or just got a little confused during shooting. DOM is indeed "seamed" tube just like HREW and starts out as a flat ribbon of steel that is then formed and welded together. Counter to your explanation of it being "solid core that then has the center core bored out", DOM actually starts out as HERW and is then made into DOM by removing the inner and outer flash weld and drawing it over a mandrel which creates the uniform wall thickness. What you are thinking of is actual seamless mechanical tube.
Just in case you don't want to take my word for it here is a direct quote and link from a steel supplier.

ERW (Electric Resistance Welded)
The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (square or rectangular) shape. The edges are forced together under pressure as a butt joint and then welded by heating the material to temperatures above 2000° F. The flash weld that has formed is now removed from the outside diameter of the tube. Once the weld has been tested the tube then passes through a series of sizing rolls to attain its precise finished size, after which the tube is then straightened and cut to length.
The material used in the manufacturing process is typically SAE 1010. This product is typically available inCold Rolled steel (CREW) for 0.060” wall and lighter and Hot Rolled steel (HREW) for 0.083” wall and heavier. The product will come in an “as-welded” condition, (often called – flash-in condition) referring to when the flash from the weld is left on the inside of the tubing, it is not normally removed or controlled during the ERW tube production process.
(DOM) Drawn Over Mandrel
Technically, DOM is not a type of steel tube, but rather the process in which the tube is finished. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel. The first stages of manufacturing are identical to ones used to make electric resistance welded tube, but in the finishing stages the entire flash weld is removed and the tube is cold drawn over a mandrel. The cold drawn process provides the tube with better dimensional tolerances, improved surface finish and the strongest weld strength achievable. DOM is often incorrectly referenced as “seamless tube” when it actually does have a seam (although it is almost invisible).
Seamless Mechanical Tubing
The seamless tube is manufactured using a process called “extrusion”. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube.
Basically there are two types of seamless tube:

Basically there are two types of seamless tube:
- Cold Drawn Seamless (CDS) normally made from SAE 1018, having precise tolerances and good surface finish
- Hot Finished Seamless (HFS) normally made from SAE 1026, having less critical tolerances and a scaly finish – Not as strong as CDS
@blazinzuk there is no malice here, just setting the record straight and educating @4wheelinfury so he actually knows what he is talking about to the masses who are going to take him at face value
yea, I know I already got set straight. See the issue is this. You have three minutes for a video like this. Anything longer and people won't watch. I will add something to the video for the DOM clarification, but just to make it clear, I asked several people about the process and was explained it the way I did. I hate propagating bad info, which is why I have asked for input into my LS swap video series that I am currently filming and editing.
That said, cliff notes. Waaaay too wordy. I need to get the point across in a few sentences or less.

but go check the vid. It has been edited
I was just giving both you guys crap lol.
@truck-oholic and. @4wheelinfury
The vids are a thousand times better than I could do.

Good on you man. I know it seems like I am always being critical but I promise my intentions are good. All I want to do, even in the ongoing driveshaft debate which I know is a touchy subject, is provide people with the best, most accurate information possible so they are not mislead.
while I am whoring out my stuff, I just started a website to keep my truck, trailer and adventure stuff in one place. Check it out.

new video up on the UPOL bedliner and rack build start
Is that stuff more 'hard' or 'rubbery'
You have a slight accent, where's that from?

Hard. English.
I'm sorry. Lol!
When you said you had 4 "pots" of bedliner I knew something was up.
If you take the truck on "holiday" with the family we'll all know for sure...
