Oh I didn't mean to imply that an RV salesmen gave me the bad advice, because he didn't. He just showed us trailers that he thought were in the 1/2 tom truck tow-able range and said that we'd need to investigate further. So no foul there.
No we're getting the bad advice across dinner table during family functions. You see I have a few self proclaimed "Truck/Towing" experts in the family that offer unasked for advice and opinions. When relatives hear that we are planning upon buying an RV they always say "buy one with a bunk room and extra beds, so I can come". To which I reply, "my truck can't pull that" and then they always say "but, you have a big Truck!" and then O ave to listen to stories about uncle Bills friend who tows a 30 ft TT with a Jeep....and it goes on and on. I just end the discussions with "I don't care what stupid *** friend does with his Jeep, but I'm not risking getting into an accident". Now my wife believes me when I tell her that my truck can't pull a very big trailer, but I just thought she should hear it from others.
Not only do these relatives offer unwanted/wrong towing advice, but we also get to listen to their bogus economic studies about the merits of RVing vs "Hoteling" and they wonder why we want to get away!
I thank you all for taking the time to offer you opinions!
