Thanks guys, I ended up calling the Freightliner hotline & they advised our local Freightliner shop on how the install should go. Instantly it was adjusted from 7 hours to 3 hours! I try not to use this shop (Freightliner Orlando) even though they are a Oasis center & 5 min from my house as they have never been very accommodating or helpful when using in the past.
Example I asked them while there today if I just had my annual service (oil change, etc) done on my generator but have run it 150+ hours in last 10 days since (due to living in it with power out here) should I consider another oil change or service and there response was "look it up in your manual"!!
All other work will be done at my dealer as Independence RV is great, in this case though I had no choice.
