Sluggish backing up

I have a driveway with an incline (about 6%). I was backing into it the first time with the Solera and the engine had to rev to over 3K rpm's to pull itself in. I was surprised it was so sluggish in reverse. I wondered if it would go in at all. Has anyone had similar sluggishness while backing up hill.

Yep, perfectly normal for the diesel Solera to climb that grade slowly. Its all do to torque of a diesel compared to a gas engine. Torque and HP are two different things. Diesels tend to produce more torque at a lower RPM than the same size gas engine. Gasoline engines produce their torque at a higher RPM. Just think of those loaded diesel semi trucks laboring up the steeper hills on the interstate.

I guess I haven't really noticed any problems backing into my driveway which does have a slight incline. But then I'm usually busy watching out that I don't hit my garage.

OK, I get the torque differences which baffles me that it revved way above 3K to pull in. Seems that under the logic that the diesel has higher torque at low rpm that it would transfer that torque to the wheels at lower rpms. Yet, it had to really load it up. Ideas?

How many miles do you have on this unit?

is the transmission due for service or low on fluid?

6% is a pretty steep hill. Reverse gear also lower than forward gears. You certainly don't want to backwards as fast as you can forward.

Dwaynerz is exactly right, 6% grade is steep and your pulling close to five ton.

Thank you all for chipping in. The coach has 1,000 miles on it, brand new. I haven't checked the fluids but will now. The driveway is an urban street driveway with a sidewalk. From the sidewalk it climbs about two feet elevation in about ten feet of depth. I built a short ramp (4 ft) to level that a bit at the sidewalk so that the stabilizing jacks wouldn't drag. That worked great, but the coach has a really tough time backing up the short hill.

An aside for background -- pulling the hills on I77 from NC to WV the tranny shifted down on only two of the seven long grades. Torgue was good in forward gears.

Another aside -- is the turbo audible? It is on many diesel vehicles.

Thanks again for your thoughts on this. I'll let you know on the fluid levels.

That doesn't seem right to me. I would research the tranny. A diesel needs a low stall torque converter. I had a low stall TC behind a high output big block Chevy to use the torque for four wheeling.
Extensive backing at 3000 rpm's at slow speeds can't be good.

BTW, reverse gear may or may not be lower. Ford's pride and joy SD tranny has a lower first gear than reverse.
1st 3.97:1
2nd 2.31:1
3rd 1.51:1
4th 1.14:1
5th 0.85:1
6th 0.67:1
Reverse 3.12:1

Again, yes that is normal as well. I have driven that route as well. You will find that it downshifts very little on normal interstate grades. Sometimes more with a strong head wind. I know many chim in here trying to add their opinion, but you have to own the MB 6 cyl. turbo Solera, to comment on unit specific questions, from this initial poster in this instance. And, no to your other question, you do not have any noticable "turbo lag" or can you hear any turbo spooling.
