Hello and thanks for all the great info here. I have a 2001 Ford F-250HD (gas burner). The hitch I have was on it when I bought it 2 years ago. I am attaching a photo of the label and it doesn't say Ford so it may be after market. The sticker says V5 with limits of 10,000 lbs towing weight and 1,000 lbs tongue weight. I have a very light truck camper (maybe 1,500 lbs fully loaded) in my bed. Finally, I have a 24 foot pontoon boat with a 70 hp motor and trailer with a combined estimated weight of no more than 4,000 to 5,000 lbs. I plan to tow my boat to the water on good level roads about 2 hours away and leave it. My questions: To use the hitch with the camper on, I already have a 2 foot hitch extension (no idea of manufacturer or rating). The label on the extension says it decreases towing limts by 1/3 but based on my above weights I would still be within limits. Can I safely tow the boat as set out above on a once every year or so basis? Also, I think that I could get by with only a 1 foot extension. Would that make the difference as far as being able to safely do this? If this is not something I can safely do, I can tow the boat with a different vehicle since it is not something I will be doing often and not that far, but I would prefer of course to use my own. Finally, I have air bags on my rear suspension so that will not be a problem. Thanks in advance. Raleigh.
