The reason for that shape and style/design I guess is for an elongated trolley system,which is
what I`ve got at present really.I`d like to try it more so if that were possible,hence the request
for those sizes.I personally find elongated type trollies have more manoeuvrabilty than the ones
presently on the market.I keep going on and off with the backpacks,although they are `the way
to go perhaps`.Guessing it would be approx.35 liter capacity also,possibly more,possibly just less.
Thanks for the offer regarding the material to be aluminum,but just for now I`ll stay with plastic
if thats possible.Aluminium might be too heavy.If ya hav`nt a back pack how do ya go over gardens,
lawn and open plan areas,up and down steps etc.etc. etc. etc??
