    All those questions about diesel engines mean little to anyone who has never owned or driven a vehicle with a diesel engine. Therefore, these questions are, for the most part, only for the owners of motorhomes and large travel trailers!

    BTW, I got 5 correct. I’m the co-owner of a hybrid which is towed by a flex-fuel vehicle than runs mostly on E-85

  2. Barbara Kirkhart, I’m glad you enjoyed the trivia questions. As far as the questions in regards to Cummins, you must keep in mind this is a trivia challenge. No one is necessarily familiar with all topics in a true trivia. That being said, your score of 12 is very good, as is your honesty. Thank you for taking the time to post both your score and your comments.

  3. Barbara Kirkhart

    Good quiz, but I agree that the very specific Cummins questions have little to do with RVing in general! I got a 12 (female, 62, not particularly technical but have attended all the technical sessions at Life on Wheels twice). I agree with Tom Liberty, that both holding valves are best left shut until the tanks are full, then drained in the sequence he describes. We generally wait until we have driven a bit before emptying, in order to be sure things are stirred up – but then, we don’t generally stay in one place more than a week, so don’t have to be emptying tanks after sitting a long time. I’ll always remember the guy I met in the Camping World holding tank chemical aisle – his class C camper had been sitting for a couple of months in one spot with both drain valves open, and he couldn’t figure out why his toilet wasn’t draining! He had a solid mountain of waste to deal with. I wonder if he ever broke it loose and was able to clear the tank!

  4. Don O, You are correct on the omission of staying in the mirror view on the right side. The reason the right side is the correct answer is that it gives the spotter a good view of the right front wheel well, a common blind spot to drivers. Thanks for pointing out the omission..

  5. I disagree with your answer for #16. I answered B because it was the only one that said the spotter should be visible in the mirror at all times. The mirror is the golden rule. I won’t back up an inch without seeing the spotter in the mirror. I don’t care wich side of the rig they are on, as long as they are at the rear, and visible. Just call me Yogi, cause I got 12 right.

  6. John

    Surprised myself with 15 right! Good fun, keep ’em comin!

  7. Randy Maurer

    I consider myself reasonably knowledgeable about RVing and camping, but only answered 9 correctly. And even though I answered some of the Cummins engines questions correctly, what does the history of Cummins engines, or diesel engines in general have to do with RVing? Aren’t these Cummins trivia questions? Furthermore, why would anyone except owners know anything about Spartan chassis or Newel Coach?

    I guess I’m just a disgruntled know-it-all wanna-be.

    Keep up the good work,


  8. Bliberty Bloberty

    I’m a female and I scored seven; but I’ve never actually set foot in any RV in my life! I’m (unfortunately) just an armchair RV-er at the moment, soaking up as much info. about the lifestyle as I can, and hoping to talk my hubbie into making our first RV trip this summer.

  9. So far I’m impressed. Such good scores, such honesty. Keep them coming, I know there are guru’s out there/.

  10. TN Cowboy

    I don’t do Motorhomes much I’m a trailer kind of folk. It’s a lot of fun and interesting thought, Thanks. Keep it up

  11. Judy

    Only got 7. still learning

  12. Traveling Whits

    We don’t know why we have to know some of this stuff but we did score 13 right and so maybe we also fell through a crack

    We had fun doing this!

  13. John Shelton

    I scored a 16 on this one. Couple of questions were specific to certain models and were not really “fair” questions. I don’t watch much movies either. (But this is a trivia game, so no hard feelings) Question number 6 CLEARLY has two correct answers. It is correct that a turbo spins at 90,000 to 150,000 RPM and higher, and I knew that you wanted that answer, BUT……… “90.000 to 150,000 RPM and higher” not also “in excess of 5000 RPM”?

  14. GMAs

    I missed one… the robin williams…

    19 is not listed.. so did I fall through the cracks??

    Lots of fun… but most geared towards the guys.. how many women scored on this test? Now if you asked … how to do something in their area… such as… get rid of the stinkie old man… ahhh gee we would be lost… I think…

    I know I can never find the keys… wallet or where the drinks are… thank goodness…she knows it all… grin…

    I was looking for how often your supposed to change the muffler bearings.. and am stumped… grin..

  15. My only thought for #8

    When hooked up to full services for a long stay, the following is one of the acceptable black/grey valve configurations used.

    I prefer to keep both closed and when either of my holding tanks are close to being full, I will first drain the Black and then the Grey to clean the hose from the Black Flush. This helps to keep my drain hose from accumulating black matter and odors.

  16. Angie

    HA. I’m not a dummy, I just play one on 🙂

    I only got 5 right.
