Motorhomes on Mercedes Chassis

I have a 2018 PleasureWay built on a Mercedes chassis which I bought new.. This is my first diesel powered rv ever. I don't want to be too wordy so I'll be brief. Never again,it was a serious mistake which I find is very costly like $500 front end alignments, $235 for a fuel filter, $1,000 for a replacement windshield, etc, etc. The worst part is when I had a check engine light come on with only having 1,500 miles while I was in Utah somewhere and I live in California, I called 3 Mercedes dealers for service and two told me they don't work on Sprinters and the third said they would service it but gave me an appointment for 3 weeks later in the month. Weeks of worry later I arrived home to find that I received a recall letter from Mercedes which addressed the check engine light issue. Another annoyance is the extremely soft and vague brake pedal. One feels like the pedal will touch the floorboard before the vehicle will stop. I'm told "they're all like that, you'll get used to it". As to the supposed "plenty of power" statements, all I can say is you must try it and then decide. This Mercedes runs out of breathe long before it reaches the top of the hill and your only salvation is to plan way ahead and downshift at the right times to even keep up with traffic. My previous rv had a Ford v10 engine and that vehicle could literally run circles around the Mercedes.My suggestion is don't take my word for it, take one out for a test drive and then decide for yourself.
