We ordered this light weight folding sack trolley from www.screwfix.com and it arrived yesterday. Just the job for transporting gas bottles etc. and avoiding hernias. It only weighs 4.1kg but is capable of carrying 70kg with a height adjustable handle and robust wheels. The really useful thing is that it will fold down to a compact 29"x 17" x 2.5" and fit neatly into Caxton's front locker.
