No experience at all with lifts--but pulling a 35'TH with a 10" lift behind a 3/5 ton pickup with a 7" lift, doesn't sound like a good decision to me.
Think about lifting your semi that high and heading off into the sunset?
Re-think this, please.
But, welcome to the forum, and maybe someone will have more valid advice.
