Do not count on that. Most gasser Motor homes come with a hitch rated for 5K but the actual tow rating is equal to a math equation.
(max combined gross vehicle weight)-(Gross Vehicle Weight)
Example. My Class a had a Max CGVW of 26,000 and a scale weight of 22,000 so it could tow 4,000.. One Chevy Lumina APV (1992) originally (Towed like it was not even there) and later a 2001 Dodge neon (2001) which cost me MPG.
The lumina was 4,000 curb weight, the Neon 2500
Two reasons the Lumina towed easier
1: no tranny drag (Axle lock) v/s tranny drag (Lube Pump)
2: Wind "Spoiling" was better with the lumina
Oh well. RV totaled (Actually that was a good thign) now drive a JEEP (Man does that sucker SIP gasoline. up to 40 MPG at 55 mph (less if I hammer down)
Just to be clear, a Class III hitch by itself is rated at 6,000 lbs trailer/car weight, with a max of 600 lbs tongue weight, not 5,000 lbs. The manufacturer rates the towing max based on their attachment of the hitch to the MH, and as you say, 5,000 lbs seems to be the magic number. But also as you show, the true amount one can tow comes down to math. My MH is the 22k/26k F53 chassis, and fully loaded with tanks full (not black or grey) and my wife and I sitting the the front seats I weight 19,880 lbs. So, in theory, I should be able to tow the max of the Class III hitch (26,000 - 19,880 = 6,120 lbs). BUT - my MH is only rated to tow 5,000 lbs. My toad weighs 4,600 lbs with a full tank of fuel, so I'm under the 5,000 lbs MH max, so I'm good.
Personally, I think it's important to get ones MH and Toad properly weighed so you really know where you stand, but I am amazed how many RV'ers I speak with that have no idea what they truly have. Spoke with a guy who had a Mobile Suites FW a while back. He was towing with a Ford F-250 and was talking about how unstable it was. I asked him his weights and he had no idea, he was just told by someone at Ford when he bought the truck that it would work. Wrong answer. I recall speaking with a rep for Mobile Suites a few years back at an FMCA rally, and he told me they recommend all their FW be pulled with a 350 or 3500 dually.
My wife told me about a post on FB where someone was towing a trailered car, and then a boat behind that. (I believe that is illegal in most states but am not totally sure). They got in some crosswinds and flipped their rig. Thankfully they were not seriously injured, but really?!? Am not surprised.
