I drove truck tractor/trailers at a very young age. However, the first time I hooked up my F350 SRW to a 39' FW the "thing" looked pretty big in my mirrors. My advise would be to pre-plan your routes the night before and use a good RV GPS unit. While pulling a large FW you have to PAY ATTENTION by constantly watching all traffic around you and behind you. I completely enjoy pulling my fiver down the road but I only do about 300 - 325 miles per day. I never want to start getting tired or daydreaming while towing so we try to get off the road by 3pm. If you are retired and/or full time what is the hurry anyway?
