Question Coachmen Concord - No Power

Hello, all - My first post.

We're looking at a 2012 Coachmen Concord 300 TS, well cared for. Yet, in a test drive, it had no power whatsoever climbing a highway grade (a long hill, not a mountain). Couldn't kick it even to 50 mph. Lots of noise and engine strain. A diagnostic showed no problems. Service tech drove it and basically said the engine is what it is. Chassis is a Ford E-450 SD V10 6.8L, 305HP, with just under 50K miles.

Hard to imagine driving this over mountains, or even towing a Jeep. We also test-drove another rv (new-2015, same size and weight, same engine) and it took the hills quite nicely.

Do other Concord owners have the same lack-of-power issue?
Is it likely that other 2012 Concords will exhibit the same problem, or might this be unique to this unit (meaning, there's a problem not showing up on the diagnostic)?
Would it have to do with the 2-valve engine (as opposed to the 3-valve typical in class A gassers)?

The service technician is blowing smoke. I'm no expert but

there is definitely a problem somewhere in there.
As for the two valve and three valve question that is because the engine compartment of a class c is tighter.

We have a 2013 Greyhawk on a 2012 Ford e450 with 2 valve v10. We have plenty of power. You are not going to go 70 up a hill. Ours will drop from 60 - 50 on a mild hill but pick up speed on the down side. The v10 does screen in the up side. Might put in a 5 star to resolve the issue.

Thank you for your reply. Hate to say it, but sounds like hot air to make a sale.

Thank you. The unit is lovely, but under the hood... apparently not so much.

Plenty of power -- or at least enough power -- is what I expected to find in the Concord. Having it chug along at 65, then face a hill and drop well below 50, screaming and churning (had to nearly shout over the noise)... well, the struggle just didn't feel right. Since we're a long way from having engine expertise, I'll have to look up what is meant by a 5-star. I appreciate hearing about your Greyhawk and the same engine; as I understand it, the V10 has been a well-liked powerhorse for its usage. Thanks much.

OP here. We've decided not to pursue this particular unit. The engine worries us, and seems to concern those who replied to my question on here as well as our sales rep; it was he who suggested a diagnostic. We definitely need some power for mountainous driving, so we'll simply keep looking. Maybe the hunt should move toward a smaller class A, and diesel. This would be our first rv, so there is much to think about. Thanks for everyone's input.

There are many discussions on here about the high revving Ford V10 and the two engine tunes that many say helps. 5 Star and Brazzels (sp)

I own a class c with a V10 and no longer panic when it screams while going up a hill.

We might have considered the screaming and loss of power as normal, had we not immediately driven another rv (albeit new) with the identical engine specs and virtually the same length and weight, which cruised right up the hills like a champ. Also if the Concord were ours to begin with, we'd certainly keep and deal with it (engine tunes or such, as you wrote), but given that it would be our first, we remain very hesitant, and are continuing our search. Thanks for the encouragement and happy travels!

I have a 2008 Concord with the V10. Took a trip from Florida to the Grand Canyon last summer towing a 2005 Chevy Colorado. I had plenty of power to handle the grades I encountered. I regularly take short trips without the tow vehicle and easily maintain 70 mph on the interstate
