    Heck I think your idea is pretty well thought out myself, and don't see any reason why it would not be a whole bunch stronger, as long as you do a good job welding and fitting it together. The existing set-up looked to be pretty flimsy and also overloaded at some point in it's lifetime. The existing frame (on the sides) with the expanded metal is carrying a good bit of the load, so replacing that with the channel will help a bunch. Some kind of diagonal brace replacing that area up front sure wouldn't hurt. That is if I understood your planning to remove all of that correctly. And a couple more stringers run down the middle would be a good idea as well. Using the size channel that fits the tightest makes the most sense to me.

    Getting it clean enuff to make strong enuff welds will be one of your bigger challenges.

    What type of welding machine are you going to use (and don't say some 115v mig machine) Chances are the underneath or overhead welds will be the ones that give you the most trouble. If you do plan on using a weak mig then re-think this and either get a bigger mig or stick weld it. If you are a good welder with a powerful machine then please excuse me...we have a quite a history here of people posting trailer projects and wanting to weld them with machine that will not provide safe welds. Safety is your biggest concern in a project of this magnitude.
    One thing you might think about is the angle has a web in the inside corner and the outside corner of the channel is sharp so they will not fit entirely perfect.
    Great job on the pics(IMO) and can't wait to see how you progress with this project

    BTW...for those who have dificulty reading the text with the larger pics I'll tell you how I read them...I simply click the "quote" and then read it and then go back and review the pics. Not perfect but it allows me to read and move on instead of getting away from the real questions

      I will be welding it with my millermatic 251.

      What is the math for the axle location? If I add 2' dovetail to the back I think I will be in the right location but now would be the time to move them. Isn't it something like 1' back from center? And center would be the over all length of the trailer. Dovetail to gooseneck.

      And also on the goosneck hitch, you have the 2 verticals coming up from the front of the deck. Then there is a horizontal that is just a piece of angle iron. Should I replace that? I plan on gusseting the 30* miter but was wondering if I should do more.

      Here are some pictures from yesterday. I got a late start as I was waiting on my consumables from hong kong for my plasma. And also had to make an extension cord for the welder and plasma.

              Day three. I cut the rest of the stuff off and started grinding the slag from plasma cutting the expanded steel off. Welded back in the cross supports I had taken out to remove the floor.

              After doing the math for the axle locations, I realized I need to move them back if I add the dovetail. Which would be a lot of work. But then my buddy realized if I make the trailer 19'8" long I can leave the two axles where they are and add a third. I was gonna make the trailer 18' over all, why not add another foot and a half. If I add a third axle it now makes it a 10500 lb trailer. I don't think I need a three axle lowboy, but why not go big or go home. If I run 6" channel and plenty of crossmember I should be more than strong enough. Then I never have to worry about hauling the cummins. But do I need to beef up the gooseneck for the 10K load?

                Just realize with three axles you cut your turning radius, not so much as cut the radius but puts a lot of wear on the front axle tires when making sharp turns.

                  as Sonora Iron wrote 60-40% thats a good start.
                  now as for the question if trailer GVW. i don't want to get in to the legal stuff. but the trailer counts as part of the GVW so look at it this way 7100 lbs truck 2200 lbs =9300 lbs. i pull my 10,000 lbs GVW trailer with my 8400 lbs skidsteer. and i wish i got a bigger trailer. it's ok around town but the trailer tires and axles really don't like the weight.
                  and nice truck i have a white 01 chevy 3500 x-cab dually.

                      Just an idea for more strength. Less weight, more strength.

                        Also, are you gonna straighten the frame right behind the axle on the right side?

                          if your going to do all that how about going deckover ?? then you can push it out to 102 inchs.

                              Red will be channel, Green will be probably angle, channel, or tube crossmembers and white will be the third axle. I don't want a deck over because I want the low deck height for loading low clearance cars. I will have a dovetail, but still I need it low. Also I will have removable fenders if I ever have to load something wider than 82" inches. Do you think I need to strengthen the gooseneck? I like the truss idea, but don't want the height.

                                When I put the channel on there I will heat up and straighten the angle and weld it to the channel.
