I have a single axle Kendon with the stone guard and spare wheel. I bought it for hauling cross country (2600 miles) twice a year. For that kind of travel I felt a stone guard was essential considering the exposure to all kinds of road surface conditions. It is quite difficult (heavy) to stand up with the guard on, but it can be done. However, then you have a head-banger left to deal with cause you essentially have to use the upright position backwards. Best not to have it on for the upright position. Not too difficult to remove...it's basically bolt mounted. It probably took me 15-20 mins to remove it, so it's not a real big deal, just a nuisance. Stands up easily w/o the guard on. But, it does a good job of protection!
