The TRX500FM1 is the foot shift, straight axle 2WD/4WD version. The boys and I duck hunt off it (yes its overloaded) and I use it for light hauling around our place. Will be dragging lots more brush and attempting to pull manzanita stumps this year in addition to the fun stuff.
I'm the original owner of this quad and its been great... except the single rear shock on the straight axle needs to be replaced.
I see Bronco makes a replacement shock but I'm also looking for recommendations and brands to avoid from you folks.
