Mercedes 450

Starting to seriously look at Renegade.
I have read several posts about the Mercedes 450, none have been very complimentary.
What is the main issue with that motor?

Most reviews state they are underpowered and have issues like head gaskets, turbos and fuel injectors. Remember, many of these reviews are from truckers using them for a million miles and hauling 80,000 lbs. day in and day out. RV use is less demanding. When I bought my coach, I test drove several with the MB 4000 and it seemed very capable. In the end we ended up with a Detroit series 60. My decision was more about the coach, it's condition and the care it had prior. If you don't feel comfortable have a qualified truck mechanic check it out. It will give you peace of mind.

I think a major consideration should be availability of service. With my Cummins ISX15 and Freightliner chassis, I can get service just about anywhere big trucks get service. Just took a 6,000 mile road trip, encountered a dripping heater core along the way. Was able to get it serviced at a Loves Truck stop where they did a temporary bypass of the core and I was on my way in less than an hour for $50. No issues or hesitation by the mechanic of it being an RV. I asked him about parts availability and he said Cummins are the easiest by far. The Detroits aren't too bad but are suffering a bit by parts supply issues but are not too difficult to work on. Not sure about the Merc motors, especially if you are considering an older rig.

Regarding your consideration of Renegade RVs, I certainly can speak to the high quality, fit and finish of my 2014 Classic which was build when Renegade was still owned by Kibbi LLC. REV Group purchased Renegade in 2016. Others can speak to more recent experience of the delivery quality of their rigs. While new Renegade rigs may have more build quality issues now than in previous years, I dont believe its anywhere near the nightmare issues I have read in these blogs regarding other manufacturers. Happy Hunting.
