Went on my 2nd wheeling trip since finishing the truck. Mechanically it performed perfectly. The lone issue I had was the power steering fluid got hot and started puking fluid towards the end of the day. It never affected how it worked but I'll need to address it before I burn up a pump. I don't think the Lexus pump is as strong as the stock truck's pump. I am using the LS400 pump with the build on reservoir right now but I will switch to the SC400's remote reservoir version when I add my hydro assist. I can use a larger reservoir that way and hopefully keep the temps down.
