Anyone had anything to do with measuring the down force on the towball using the item show on this web site . Looks gppd may need to get one just to be safe . Anyone got another method of doing it with a +- 5% error factor .

Thought the same. Have got on loan a Haymen Reece one from a mate for the moment but if these really do work I'm all for getting one. The HR is a little bulky to cart around but once I have the loading sorted out it should be okay only requiring the odd inflight check when mum loads the available space with gifts for the kids.

while camping Xmas time.....Rosies brother came up with a bottle jack with a guage on it.
jacked up the draw bar....giving me an idea..the tow ball weight was 120kg...bit heavy for a campertrailer

Bathroom scales work well up to their limit and readily checked for calibration by weighing a known volume of water (1 kg per litre)..
Re a tow ball mass for a camper trailer - 5% - 7% is ample.
