PSchw, I found ample with the Airstream but other than the propane regulator replacement, I fixed them myself. Some poor engineering, some poor installation. Some just poor dealer prep before delivery.

I'll expect no less from RT but I do, as all RT owners, have the "ear" of the president. Not so with AI and Thor.

Biker bill you right and I followed your postings.
For me to was close between RT and AI the AI won it looked better to me and yes look does not mean it is better and looks can deceive as well availability and dealer willing to take my old on in for a good price as well as the financing offered.
So far I like my AI but I also know there is better out there and maybe in 5 years or so I can make a change.
So I want to learn as much as I can from you about the RT as I can so I my make a educated pick the next time.
Thanks
Peter

PSchw, I bought the AI from a dual dealer: RT & AI. Went to buy and RT but he showed me the AI and with its longer body and nicer cabinets we bought it. Hate the Suburban furnace and the single bath door. RT now builds also on longer body and with diesel heat/boiler and the E-trek and with the improvements in the last year on the Mercedes chassis, we bit-the-bullet. Our more local RT dealer gave me a MUCH better trade in. Probably close to $K more than the AI dealer was willing to do. I pick it up on Tuesday.

Bikerbill looking forward to read your opinions on all the goodies on the RT. I love the idea no propane and no generator. I looked into a Dynawatt generator from Europe which is independent from the rpm. With up to 5000w you could run the AC furring driving without running the propane generator.
Thanks for sharing.
Peter

Do they make a 60Hz model? And the spec sheet I found says it makes no power below 3,500 rpm.

Yes they do. The 3600rpm are on the generator and the run a 1:3 which comes to a motor rpm of 1200rpm. It is used in Europe for emergency vehicle which a lot are Sprinters.
It looks interesting but I don't know enough about it to really make a good judgement maybe somebody out on the forum looks at it to see if it would be something worth to try.
Thanks
Peter

I think I saw something about a secondary generator over on the Sprinter-Source forum. I believe it requires an add-on kit from Mercedes to drive it. Or you can order it that way when it's new. You might check over there. IIRC, it's an expensive proposition.

Yes I saw it too but it is rpm dependent so you only can use with high idle. The Dynawatt is not so running the main air would be no problem.
I know it is not cheap but what is. It's more about the possibility and if they would work as well if somebody at did it already.

Roadtrek is installing a generator that is 3-5000 watt, rpm dependent. You only momentarily take it to high idle to "start" the generating cycle.

Yes, you can order the MB chassis with a 2nd mounting bracket. And yes, you should be able to install one later, BUT there is some heater hose rework that has to be done. Much simpler when ordered from factory that way.

The high idle feature is a necessary option for any Sprinter that is idled for a prolong period of time. That's why ambulances have this feature, it is best for the engine. Jim

The high idle part is also available aftermarket from a German guy from the north-west I did get it but did not installed it yet.
Now on the RT can you only make power when you idle?

On the Roadtrek website it says:
"At idle it feeds 3.5 KW of power. When driving, it is even more powerful and charges at 5.5 KW. "

The high idle is for engine protection also. Can't idle the new diesels for long periods of time day after day like one could the old ones. Not really a huge increase in rpm, can't remember how much. This might decrease warmup times in winter, if memory serves me well. Jim

zigzagguzz, you can idle the new Mercedes for up to 3 hours, per my phone call to Mercedes. As an owner I asked. And they assured me 3 hours at a time would not be a problem then just take it for a 15+ minute drive on roads. And then I could go back to a 3 hour idle.
