I don't know if I'm regretting not adding the Max Tow package to my pro. I ordered the Tow Tech package, and was going to add on the max tow, but didn't like that i had to add on the the 9.6kw pro power onboard package (since i can't power my home with the pro model .such b.s.). So for almost $2k, i can only tow 2,700 more (not 10k lb like ER can) and can't power my home. and just like that, i talked myself out of max tow package and am once again happy with my order. Wow, typing therapy does help!
