Hi Julie , you cannot calculate nose weight you have to measure it , with a nose weight scale , varying types available , I use a TLC electronic type just pop it on you tow ball and attach the van and hey presto it gives you nose weight , you can then adjust it to the specified weight for you vehicle by moving or removing items in the van .
Most domestic appliances will work on a 16A hook up , kettle, toaster, tv ,microwave etc, just try not to use them all at once and you'll be ok
