Our last motorhome had a rating of 5,000 lbs in the manual for towing. While I was under the MH checking something else I noticed the label on the tow hitch. It was 3,500 lbs. Best to check both before you begin towing.
While in a campground I noticed a MH with an aluminum trailer that had one of the new Thunderbirds on it. Since it was a gasser, I was curious about the combined weight of towing the trailer and car. I went over to see if there was a tag on the hitch. What I saw was scary. The welds on the hitch were tearing loose from the frame. Way too much weight for the hitch.
