We had a L3130 with a Curtis hard side cab that worked well. The install and the fit were very good. It took two guys about 6 hours to install the whole thing then a few more hours of fine tuning. We then wired up front work lights, wipers and a heater. With the exception of the work lights all accessories were also puchased from Curtis. There is nothing like a factory cab, however this is a close second. If I remeber corectly our former dealer wanted around 4K for the install with only the heater. We did it with two guys and saved a bundle. The key is having help if you do install yourself. Send me your e-mail address I have pics of the finished job. hope this helps.
