I was having the same issues when it came to lifting my Otter into the bed of my truck by myself. I got a few 2×4’s and made a very inexpensive ramp and now I can easily slide it into the bed
I recommend using a local contractor. I had my home re sided with hardyplank and they did a awesome job and they do roofing too and they are out of Zimmerman. The company is Craftsman’s Choice and everyone there was great.
