It's damn hard isn't it .lol

And lets not forget about the single sided forks they make now They wouldn't make them if they failed .
My theory is if the mounting point is strong enough to not flex on one side as this is it should have no problems holding up ( I could be wrong but we'll find out in the long run ) I have built trailers before out of other materials to save on weight ( and bolted the wheels as every trailer has them ) and they have all ended up failing simply because the frame wasn't strong enough and if I only had them bolted to one side on those trailers they wouldv'e lasted about a week . but as I already said the angle steel is 45 x 45 mm x 5 mm thick ( it's heavy duty ) so I think it'll hold up very well but we shall see .
