No experience with it but it looks like a very interesting product. Shouldn't void the warranty as they aren't modifying the trailer. I would think it would be really light on tongue weight compared to a trailer actually built to be a GN or FW trailer. But, it would still probably have more (and better placed) tongue weight than the trailer did originally.
The area above the hitch would possibly be built with a storage platform for generator, firewood, etc.

you mention tongue weight, this is specifically what i am trying to wrap my head around. this hitch weighs 300 and some lbs but that won't specifically be added to the tongue. some of it might but i imagine most of it will be in the bed of the truck. my f350 drw wont mind that. or am i thinking of that backwards??

my trailer empty has 16% tongue and if i haul my 2k lb sand rail, ( mid engine, 60% of that is in the rear with out occupants) it is very tongue light. as in it actually walked my drw to the point i had to throw the brake controller to straightened it out, twice. i then pulled over and began shifting weight. that was a sudden diaginal gust of wind and i had an anderson wdh system. the wdh is of no use as this trailer still doesn't squat my truck to that point, empty or loaded. i pulled the two spare tires off the rear and put one under the bed/cargo area and one in the back of the truck. moved 2 tool box's out of the bed of the truck to beside the bed in the nose of the camper. apprx 100 lbs for the 2 tool box's and that instantly made an 85% diff.

a true fiver or GN would be closer to 20 to 25% pin. i have two spare (235-80x16 , 14 ply on steel rims, feels like 65 lbs ish) mounted underneath by the rear ramp gate. they have a steel H frame welded ( imo tacked ) to the I beams. https://youtu.be/vn9t9gT44cw .... https://youtu.be/HKIK6FRUR50 .....https://youtu.be/Mqo3TrNlXV4 i guestimate 150 lbs for the whole assembly. if i were to add this bpconverison i would move that entire assy from the tail end to right against the end of the a frame , under the chassis. there is an open spot identical in size as the spot in the rear is. that would relieve 150lbs off the rear and add 150 lbs to the nose. not sure if that would equate to a 250 - 300lb tongue weight increase over all or not? i also added a 50 lb steel tool box to the nose where the batteries would go. put my hoses and what not in it. could make it 20% ?? i think the GN would def add leverage and as well as control as far as sway control goes. that is my opinion, and that's what i am really wondering.

i designed the floor plan to pull my sand rail in, rather then backing it in. the front track width is 80" wide and cargo width for the front is 88" on the floor. the rear is 90" with paddle tires and 84" with scab wheels. i really don't want to swap wheels if i don't have to as that was part of the reason for the custom build.

i have considered simply moving the spare tire assy forward but i know there is a point where one could be to tongue heavy or is that incorrect? we do use it as a camper a few times a years and really don't want to move tires for different trips if at all possible. i have 7k lb ccc and only put 3500 lbs in it so that isn't an issue. the tongue appears to be built out of a more appropriate wall thickness then some i have seen. still don't want to overload it though.
