The Blue Ox failures reported lately have been with the Avail which is a 10,000 lbs steel tow bar. I have the Ascent which is a 7,500 lbs aluminum and I have had no problems.
You will not know about the hi/low (drop receiver) until after you decide on a baseplate for the CRV. You want the connection on the car to be within +- 3" of the hitch to make sure you are towing level. These are not usually necessary on a DP.
