We are hoping to join the expanda family asap. We are looking at buying a new 16.49-4 once we have sold our 2010 flamingo st. Our tow car is a falcon wagon which we intend on keeping for some years to come. Our next car will be either a 4WD or an AWD. We are undecided weather an onroad or an OB would be better for us because of the tow ball height and how a falcon would handle an OB. I have spoken to our jayco dealer but he hasn't got much advice for us on falcons towing OB's. Have even considered when the change of vehicle comes a change of height to an onroad model? Was wondering if anyone has any thoughts or advice?
