Thanks Guy, I am familiar with how to get a nose weight but you have met me. I can bench press a donkey.
But I can't even get the nose wheel off the ground on this trailer. The draw bar is very long so the pivot point is a long way back. Ordinarily this creates good leverage, but with the batteries and nose cone inside that triangle it has the opposite effect. I don't need really to know what the weight is to know it's huge. It also points down slightly - even more now that it used to which has a multiplying effect in terms of weight transfer.
I don't think our scales would survive the trailer being put on them. I must to move the batteries over the axle which effectively will neutralise their effect. (In simple terms) There's a fridge / freezer, two massive gel batteries, a generator, fuel, gas, tools, awnings, floor savers not to mention the draw bar and NATO ring all inside the pivot. The trailer actually snapped in Turkey with its previous owner and had to be repaired. The design makes it tow beautifully but really the axle needs to be further forward. Which I can't do.
That said I love it to bits. Just needs a mod.
