His answer was amusing. 

Is there a grain scale nearby that weighs in 3 sections? If so ,if it were me I'd arrange a time when convenient with the scale people  to weigh the trailer with the rear of the frame supported with jackstands on one pad and front of the tongue supported on the other . Then calculate how far back the axles would need moved to get you 10 percent on the tongue. I;m betting it would maybe only need a few inches. Can the wheel wells/fender be modded to look right . You are pretty handy after all.

Yes it was amusing,  put a smile one my face

The only thing local is a cat scale. There is a coop nearby but they weren't willing to let me weigh the tru k and camper l, a while back. I did order. Weigh safe hitch so I can weigh tongue weight.  My thought was to run to the cat scale empty and then measure tongue weight. If I have a base weight then I can see what the rail pulled in vs ba ked in does. Backed In is just a pain in the ass. But.....it is my theory that if the winch is well maintained that ill be just fine

As far as wheel wells go, there are none, I ordered this one with out skirting which means no wheel wells. Wouldn't be that hard to move the axles....in the grand scheme of things.  Looks like scotts rail will have to be backed in to fit. Might need a better winch!

So I thought I would re visit this idea once more as this custom fixer upper tows like shit when loaded with the rail. So tongue light it wags my dually's back end.  With the sand rail pulled in that is. It cN be winches in backwards but its a pain and defeats another reason for the custom build.

So I like the bolt on gn idea especially as it adds 350 lbs, initially. I decided to reach out to the company to ask some specifics. Per our conversation, he stated it does add 350 lbs tongue weight but that the 6' extension reduces the load on the rear of the truck up to 30 % depending on trailer build.  All sounds good and I would still need to transfer the spare tires to the nose.

I noticed their site states, tested by an independent company to 10,000 lbs. I asked if that is a 10k lb pin weight rating or gross trailer weight...... they responded. Ia email that 10k lb rating is pin weight.  No other information either so I sent another email asking about what the gross trailer weight is.  They responded stating that it is their theory that if one has well maintained brakes that the gtw will remain on the trailer axles. I will post pics of their responses. I got a chuckle out it for sure lol

Their answers don't instill confidence so I think I'll scratch them off the list of ideas vs ba king it in.

this is soooooo true

I know I've given you a rash of crap over your toyhaulers but I do agree with you. It is amazing how bad the trailer industry is in general AND they just keep getting away with it. Of course they know they will likely only sell a customer one and never see them back. Not much incentive to whether the customer is happy I guess.

I think you officially have the longest post ever posted here or maybe anywhere!!! Hopefully the message will be appreciated by prospective buyers. There needs to be more people willing to speak up like this with facts/documents and pics to back up what is said. Good post.
