I have been lurking for several months now, didn't know about this board until I tried to post to RVTalk on yahoogroups......but I'm glad I found it.........Anyways, my husband and I are really newbies and have not purchased an RV yet.......We have read alot of books and been on alot of websites. We bought the book "How to select, inspect and buy an RV"by Gallant and the CD that rates RVs. We also have alot of material on how to select the proper sized towing vehicle. We have not purchased a tow vehicle yet. We have decided we are going to buy an 5th wheel. Now we need some advice about a towing vehicle, alot of what we've read is complicated or we are making it complicated and Gallant says we should know what we're doing BEFORE we talk to a dealer. Here is the first(probably of many) questions.............if we are looking at a 5th wheel with a GVW of 15,000 and a hitch weight of 2,500 would a F-250 diesel with a towing capacity of 15,900 be enough of a vehicle??? Will we need the F350??? Any advice, comments, etc would be welcome........we are really confused....
