That sounds good.  5/4 deck, 4" channel sides, 2 x 2 x 3/16" crossmembers on 18" centers.

Are you going to use torflex axles, or spring?

If you are building it specifically for hauling the Drak/Prowler, I would line them up and measure the wheel spacings, and try to put crossmembers directly under where the tires will be setting.  Because of their widths, they will be easy on the crossmembers with the load close to the sides.

Lumber is my field guys.IMO DO NOT use 5/4 decking.The shrinkage and splitting due to the shrinkage will be much greater.Use 2X8's . Should be approx the same cost as 5/4 now and much better. You can easily span 24" and not worry about where the crossmembers are in relation to the load carried.

Lumber man has spoken!  I can't disagree.

My wife believes that I am going to build a deck on our house this year. :P  I was thinking of going 2" instead of the 5/4 for the same reason's.  Mainly I don't want any spring in it.  I wanted to go with the composites, but just looking at it on the rack, it bows very easily, and for the cost, I can't see that it would be worth it.  What do you recomend Fabr?

I would have thought 2x8 'lumber' would make it rather heavy?

2X8 dimension lumber seems to be the "norm" for trailer decking around here to...

Springs, Hung right to the underside of the 4 ", I am thinking to put the c out as well, Easier to weld cross members in, And a different look...

I like not needing the rail for strength, and as an added bonus better access.

The weight of the 2x8 will be offset by needing less crossmembers.

Im not dovetailing it either, I will have a 4' gate that folds in the center so upright it is 2' Shouldnt drag to badly, I will build the gate out of 1x2 tubing standing 2up and then cap the rear with a 2x2 angle... so it flushes better with the ground... Should be cake to build that way, Ill have the steel supplier cut all the cross members to length, Front and rear rails ill put the c in, and the side rails ill put it out, No 45 cuts that way either...

I am half tempted to go 2x3 angle for the lower rail and 2 x 2 angle cross members, then a 2 x 2 perimeter rail with a 4" c tounge...

Did you price the 4" channel?

Do you still have the bandsaw?

Need to kind of figure the deck heigth with the wheels/tires/springs/axles that you plan to use, and see if it makes sense for the tounge to run under the  trailer deck, or to join in at the same elevation as the side rails.

Can you do a drop axle with the axle's/springs that you are looking at?

I am kind of partial to a low trailer deck for easy loading and unloading, and not having the cargo above the truck top.  Probably won't be a problem with you van but you might look at how tall it will be if the deck ends up being 20" high.  I don't mind dragging the ass now and then in order to get a lower heigth.  With no dove it really won't be a problem dragging anyway.
