I am changing RV's and am looking for advice from people on travel trailer towing (eg. how large is too large, etc.) and will be inquiring as to what experience/success/problems people have had with specific makes/models. I have recently sold an older 24' motorhome and purchased a 2004 f350 super duty with 6.0 diesel. We are looking for something that the wife and I can live in for a few weeks at a time, yet feel comfortable towing. We live in Alberta and are likely to go just about anywhere. We will also use it for occasional trips with the grand children as well. Hopefully, I will get my inquiries into the appropriate threads.
