Im considering purchasing the following to tow my 17ft glastron:<br /><br />1997 Ford Explorer XLT<br />- 4 Door<br />- XLT All Wheel Drive (Does have 4WD low/High)<br />- 4.0L SOHC Inline 6<br />- Automatic<br /><br />Would this be safe? Would it be adequate? It doesnt have the towing package upgrade...
