Getting ready for a 3K mile tow w/ 5th wheel

[boatguy]

It is more of a quick side to side shaking. It is not very bad because my wife did not notice. It concerned me because I have towed many boats through the years and I have repaired a few that got away from their owners while towing. I was thinking tongue weight or height but I am completely new to the 5th wheel style of towing.
I am going to service the tranny. I would rather go for a synthetic fluid. Is there a synthetic replacement for mercon SP ? And will it blend ok with the old fluid that gets left in the converter?
Thanks,
Alan

Ok that won't be the rear end then. maybe like another sais its in the trailer. We have synthetic replacment for Mercon yes. It will blend just fine with what is in there now.

I just looked at the Amsoil website and they have no replacement for Mercon SP. They have Mercon and Mercon V but no replacement for Mercon SP. This is a different oil and MUST NOT be confused with Mercon or Mercon V. You are misleading people here.
