I have been pulling a 5th wheel for 11 years with a B&W and have always been very happy. I had a 2008 Eagle 291RLTS / 2008 F350 SRW and now a 2017 North Point 315RLTS / 2017 F350 SRW.
I got the TrailerSaver BD5 from Hensley Mfg. the customer service was great and the hitch arrived in 2 days. The price was $2995 + $150 shipping . I had to pick it up at the shipping terminal. It came fully assembled.
The hitch is very heavy and looks to be well built. This is not a hitch you are going to want to put in and out of the truck very often.
We put 600 miles on it this past week and it is Absolutely the best thing I have done for the towing experience to date. There is no doubt in my mind this should have been my first hitch. If you are going to pull a heavy trailer a air hitch of some kind is the thing to get.
On good to moderate roads you do not fill the trailer at all. Small bumps and bridge transitions are nothing. On rough roads you can really see it working. There is no doubt it is taking a lot of stress off the trailer.
All I can say is this thing works great and makes for a very pleasant ride. If you are on the fence about one just jump off and get it you will be very happy.
