Suitable trolley

Hi guys
I need to buy a trolley, not Barrow I have one of the large plastic seatboxes with octopus mainframe and legs with the large mudfeet im wondering what the best trolley some of you may have because would the mud feet rub on the trolley wheels as these sit below the bottom of the seatboxes ?
Thanks rob

Have a look out on ebay for the Octoplus wheel converstion kit. You remove two legs and fit the wheels to the frame. At the opposite end you fit the trolly handle that's part of the kit. Worked a charm for me for the best part of twenty years, until I changed my seatbox.
