Leah, I'm sure they'd be happy to tinker with handling and get it tracking straight. can't imagine they'd remove the Safety plus and install a blue ox for only the difference in original price. They are so far away, it is a pain dealing with them. DW has to follow me the 50 miles and take me back the next day. I could tell they took my Beaver for a test drive, it had 4 more miles on it than when I dropped it off. I can't imagine that they thought it was natural to pull to the right. Maybe they thought it was the crown of the road? Should have taken your advice and waited for the Blue OX. If one more small adjustment does not correct it, I will probably remove the Safety plus and put it up for sale.
BTW, no one answered my question about "What does it do".
It is simply a spring loaded shock absorber tied to the frame on one end and the tie rod on the other, preventing the tie rod (steering wheels) from making sudden movements and the spring helping it stay centered. I have no doubt it increases safety in a blow out but I doubt it will improve handling in any way.
