I need some help here

Guess Ed and Jim made that UTV Rack for Barrys Rig to go on top of his bed in his new truck

Any-way I was checking it out, awesome job guys and it gave me the Idea to make My 60" by 120" Trailer Wider

So I do-not have to buy another Trailer to haul wider rig around

I need to make it at least 76" Wide so I can Drive wider than 60" rig on it

Who can help? I plan on having it done this winter

Here is a only pic I have of it

Looks like could weld or bolt 2 10'' wide by 120'' Rack Platform on top of steel railing

A wider rig than could be loaded on it than

Will raise the center of gravity above fender wells, but will give me storage under rig as well

Has 3,000 lbs total weight capacity

Who can do it?
