here's the deal, the tongue ext. (factory) on my trailer isn't long enough. when i extended it there is enough weight to bow the extension so that it is a real bear to push back into the tube. so now what i want to do is have an extention made that slides into a bracket under the trailer tongue and with a ball which is inserted in the coupler. question ,it's a 3500lb trailer, i have 8 ft of extention and want 12 ft at least. my local trailer guy couldnt give me a spec on what size stock to use. i have 3"x4" tubing on the trailer (and it wasn't enough to prevent a permenent bend to be placed in the ext.( sorry i dont have the wall thickness at hand right now.)). the tongue wt about 300 lbs . with 12 ft of extended length i figure the stock should be 16 ft long. anyone have a suggestion as to wall thickness and tube size ?thanks in advance. mg
