On the topic of the Roadtrek RS E-trek, we have been copied for many weeks
now on many comments, and on much of the discussion on this Yahoo forum on
Your comments are useful to us, and we appreciate hearing your speculation
and ideas. I get little clips here and there, and I really can't monitor
all different forums. I struggle to keep up, in fact doing much of my
online work at night.
There have been engineering questions raised here that Joe cannot answer,
as the answers are proprietary and we have not released them to anybody
outside the core design and service staff who need the info.
There has been a question raised about component variation in the first few
E-treks. There is constant change, much testing, and development of new
systems with various components on the E-trek. In the end, we have found
good quality parts of several brands, that meet our exacting standards.
In development units, it is very normal for there to be minor component
variation. All our new units in development are like this. Always have
been, and always will be. We will not throw out a perfectly good inverter
to make everything identical. That would be foolish and unnecessary, when
they function perfectly.
In response to the question regarding advising owners on the E-trek, I can
tell you that it is not a good idea for people on this forum, unless they
have engineered drawings, or a very significant experience with designing
and manufacturing highly engineered electrical systems, to give any advice
or explanations on how the system functions. Roadtrek staff have the
training, expertise, and the drawings to do the job safely, and
efficiently. This product is far too new to do anything else.
I have explained previously that the system is proprietary. And you can
look at it from a thousand different ways, but what makes it proprietary
is, in fact, also proprietary information, and I will not release that
information.. Speculation that I have read, is simply wrong. If this
could be done by bolting parts together, everybody would do it.
To answer another question, the unit has 1600 Amp hours worth of battery
storage, (An amp is an amp) The unit has a daylight Solar panel at 240 W.
The unit has an engine generator. The unit has optional lithium batteries,
and an optional Fuel Cell generator. And it has many other features that
can be studied. Some are beign upgraded, some the option prices are
dropping as suppliers continue to work with us on this incredible project.
One of our owners used an E-trek for 38 hours without charging even once
(solar only), with AC running for ten hours at night, and all other normal
usages. They ran the engine for 40 minutes to top off the batteries, when
the inverter sounded a quiet charging alarm for them. Then it worked for
another couple days. Easy boondocking, was the comment!!.
Another owner lasted three days, with no charging (other than solar), and
then had to go and get water. We are installing another 12 gallons of
water in the E-trek, to allow an extra 2 days of boondocking as a result.
Great owner feedback. Great performance of the E-trek.
This experience has been fantastic, and we look forward to continue to make
our product better and better and hearing your ideas and questions!
This cracks me up. People don't think it works? Based on what? Have they seen
one, used one?
All I can say is it performed flawlessly for me as I headed south last month for
a quick trip to Georgia and Florida. I didn't get a chance to put it to multiday
use boondocking but I ran air all night on batteries in the Georgia woods and
had plenty of juice left the next morning.
I am not an engineer.
But I can say that I know I could not have done that on the RS Adventurous I had
I don't really know "exactly" how it works or want to undertand what wire goes
where and what every little reading is.... I just want to use it!
I've read some of the so-called "experts" here who have voiced all their doubts
but, seriously, why would Roadtrek sell something that didn't work?
I am delighted with every single part of the eTrek I have experienced so far.
I wish it was warmer so I could use it more! I have trips planned every month
now going forward and will be glad to share what I experience.
But please now I don't blog and write about every connection and all the
I write about the RV lifestyle. That's what I concentrate on.
And, so far, for the way I like to RV... the eTrek has been my dream RV.
I don't mean to sound flippant. I understand people have technical questions.
But, again, I'm no engineer. I'm just an RVer who chose an eTrek and, so far,
is very happy.
Technical questions should go to Roadtrek... not me.

Would you care to weigh in on this?

Hi Folks, another quick note.
Wow, I just got a really angry, frustrated email from an angry armchair
engineer this morning, who demanded that we release drawings and proof the
He sent me calculations showing how it could not. And those calculations
were completely incorrect, mainly because of the assumptions made by the
He says we only have six batteries, for instance. He SAW a photo, that
proves it. Well, I guess someone stole two, or maybe he missed them!!
And the general tone amongst some of you is the same on this forum. The
fact is, most of the assumptions were completely wrong.
This system is really complex. It is not something you can reverse
engineer from a couple of dealer photos, nor is it worth your time trying.
If you don't believe, that's OK. Some people don't believe that men were
on the moon. I am ok with that. We are really comfortable with the fact
that we can reach out and touch these units, and they work!!
