In spite of all the naysayers, I used a fixed arm Reese 5000 lb. capacity towbar for many years on various Jeeps. IIRC, it cost about $145 at Walmart many years ago. Just for grins, I looked at a similar Reese bar at Walmart a while back, and it is now $165. It is very similar to the $65 Harbor Freight towbar.
That old towbar did the job just fine. I was even able to hook it to the coach by myself! Since so many people do not want one, security at a campsite was not a problem. If I did worry about somebody walking off with it, I just wrapped the safety chains around a tree and padlocked them!
Now, since I felt it necessary to have 6000 lb. capacity, I have a Roadmaster Stowmaster folding towbar. I'm not impressed by it. The major saving grace it has is that it was $250 on craigslist, and it has a capacity of 6000 lbs. While it is "easy" to hook up to the coach, UNhooking can be a total PITA!
But, it does the job it was made to do, that is what is important.
