We bought from Rob (the owner) at Great lakes. The purchase went just fine, the PDI and pickup could have been a better experience for us. As we were told we would be able to back into their shop and setup our hitch before leaving. We were in the sales office doing the paperwork thing and the shop guys drug it outside in the 5 deg snowing like mad weather and locked the gate and left. (I am still mad) We just put it on the hitch and drug it home, 3 miles all city driving.
I have had it back to the dealer a few times for warranty work and it never goes as easy as it should. Things not done, others made worse. The last time I was in there they tried to charge me for open invoices for old warranty repairs. (still mad about that too)
It seems to me that this dealers specialty is out of town sales. They know that the units are not likely to return for repair so they don't seem to thrive in the repair work end of things.
They also have a fast turnover rate of employees in the service area.
They sure do have the ability to sell trailers reasonably priced though.
If I were you I would ask for a better discount.
