I have some good experience here. I have one...the same one in Bryans first pic. I go to BC a lot to fish and saw them often up there. I researched places in the US to get it and Eide came up; this was about 5 years ago. I ordered one from them and had to do the install myself. A major pain. And it was a simple motor that used an electric screw driver to drive it. It basically sucked for my nearly 200 lb Koffler Pram. It was way under powered and I couldn't get it mounted properly on my truck. I sent numerous pics to the Eide owner and he tried to help, but I was overall really disappointed. So, the next time in BC I talked with some dudes and they said. "4 Boys. You can get it installed at 'Cap It'." This is there website:
https://www.loadmyboat.com/ So I hauled my boat up to BC in Abbotsford and had 'Cap It' install it. It has been fantastic ever since. Power is wired to the truck battery and a key fob drives it remotely. I can load my boat myself. There is a place in Bellevue that carries the same model, and will install it, but after talking to them on the phone, I didn't feel like they were very experienced, so I decided it as worth driving to BC to get it done by the 'experts'. It is super beefy. And I have had it transferred to 2 different trucks (Tacomas) over the years. It uses nylon ropes to load your boat and it is important to get the ropes cut properly per the length/weight of your boat.
