I got to be honest with you.I am aggravated abit because I gave you a ref to the best RV site on the web and I can tell you never even bothered to look by what you are posting.That equals to any of the advise anyone gave you and you not taking it.It is kind of frustrating.BTW-a trans shop telling you a trans can handle 700 hp needs to put on their big boy pants.Because 700hp means something different to a 1800lb vehicle than it means to a 8000 lbs one in terms of a trans.Sooooooooooo what they said logically means not much.
