What else to do?

[RobRocks]

We just picked up our new to us HR Ambassador from our trusted diesel mechanic after having him change oil and filters. We wont be accruing a ton of miles on this unit but will continue to service the engine once a year on his advice.

What else should we be doing/looking at on a DP??

As stated, this is all new to us. (we've had plenty of RV's, just never a DP)

Also, after picking it up from the mechanic we filled the tank up as ive heard storing them full is key. We took it for a little road test (we love driving riding in it) but noticed that a 10 mile jaunt up the pass and back home the fuel gauge had dropped between full and three quarters tank. Is that normal?


TIA

We just completely serviced ours. I could not believe how nasty the rear end oil was. Glad we did that

Probably not, you might not have been full full from the get go.

Full full is when diesel fuel spills out on your shoes. Then you know it's full.

Whatever you do, don't open the other side while filling from one side.

and what year HR and which engine is in it?

You might want to think about fuel additive. Lucas is recommended.

I second the Additive! Even better than Lucas is Diesel Kleen.
Congrats and enjoy!
