So I have a 12' tandem axle trailer and to be able to put a bed cover on my truck to keep fertilizer dry, I moved my 200 gal. spray tank to the trailer. It is maybe a foot from the front rail and weighs almost 500 lbs. a little over 2,000 filled. I have ran this rig this way for three years with a 03 GMC 2500HD factory hitch. Usually I don't fill the tank all the way, but I will have to with a part time guy with me this year to fill two Zsprays. I know the obvious solution to getting the weight off the tongue is to move it over the axles, but I don't have a side gate. So I need the tank in front to load machines in the back. Thoughts? Is this unsafe? I was thinking of having a Reese heaving duty hitch with 2k tongue weight capacity put in.
