We are towing the 175BH with a Jeep GC Overland 4x4 v6 and it has been a good match to the trailer.
I looked very closely at the Blue Ox and the Andersen. They both would have worked great but ended up deciding on the Andersen. My main reasons were:
1) The hitch itself was a lot lighter (the Jeep tongue weight max and payload max are limiting factors to how much we can tow...)
2) had great reviews from other people with similar size trailers
3) super easy to install
4) super easy to use (simple connect and disconnect process, and light enough to easily take the hitch off when not needed)
I bought it online and had it delivered. I then installed it myself in the RV dealer's lot when I picked up the trailer. I think it took me about 30-45 min.
We have towed a few thousand miles this past summer and the hitch worked very well. No sway, pitching, etc. And its very quiet.
Here are some pics of our setup:
Regarding trailer weight -
We were coming home from a recent long weekend trip and had 2/3 full grey and black water tanks. I weighed my combined rig of Jeep + loaded 175BH before dumping and the trailer itself was about 4500 lbs. I wasn't able to get just the tongue weight but it was good info for me to keep in mind next season that running with tanks pretty full, full propane, camping gear, etc can definitely add a decent amount of weight to that dry weight.
I added one of those tongue weight gauges to my wish list
