If the forward trolly holes were spaced correctly, the PA could be balanced there as a pivot point with little 'lifting weight' involved like the rear holes require.
For me, the big problem is rolling the PA over to take the wheels off. I've usually got 'stuff' in the PA and either need to unload or dump every thing.
I will give the more forward holes a try, thanks.
With me using the back holes for the wheels getting them off is easy, just pick the back up higher till they fall out. Now putting them back in is different, I roll it on its side. I haven't had anything fall out though. I always double check for everything before I walk away, and I do the same at the vehicle, to make sure nothing is left behind at the lot.
