jornvango, I installed my Stable Lift for use on my SRW truck. I had to remove it and have to modify it for my new to me DRW truck. For me, it was more time consuming than difficult. It is necessary to remove some of the appliances for the install. Each TC is different.
I suggest calling Stable-Lift and ask for installers they may be aware of closer to you and what you should expect for hours to install. Ask if there is anything special you should do or know to install the lift on your particular TC. They are very easy to talk to and will work with you.
