I took the Roamerdrive unit out 3 years ago. I failed in catastrophic fashion the first time, leaving me stranded on the roadside. They claimed my driving style and having a chipped ECU did the damage. Truth, I drive my truck like an old man... it's a diesel truck, not a race car. There is no way that a small amount of additional power is going to create issues when driven 99.9% on road, under minimal load without towing. It's their way of getting out of warranty.
None the less, being that Roamerdrive is only a few miles from where I was living at the time I took it to them and they rebuilt it.I had bought it from them directly, and took it to them directly for repair. Once fixed, I picked it up and It was reinstalled at my local shop (on my dime) and right away was making some unsettling grinding noises. Turns out they said there were a 'few bits" still on the bench after the rebuild, but apparently not crucial. I refused to pay for the rebuild until it was working correctly, and was not willing to pay for another re & re based on their rebuild error. It's a standoff.... I eventually removed the unit and have left it out. Worst customer experience of my life.
I try to support local businesses, but I can't in this case. Then they call my local shop where I paid to have the unit removed and reinstalled, telling them they "owed Roamerdrive" for the rebuild and if they didn't pay, they would not support them as a dealer. Brutal.
Just my experience...
