Question Location of Slobber Tube & Extension

OK...I know where mine is at so my question is where is yours at? This is most pertinent to Newmar owners on Spartan MM chassis with side radiators circa 2006ish. I'm trying to figure out if a previous owner moved it or if it came from Spartan/Newmar that way.

First, I'm asking this because I am reading a couple threads about stopping blow by from making a mess and so far it seems most of those participating in those thread seem to indicate the blow by tube is at the rear of the coach.

Second, I'm asking if there are any known issues on extending a slobber tube. I think I have read that extensions need to be done carefully. The biggest issue is to make sure there are no pinches or valleys for moisture to collect and later block the tube.

As background...

Mine is located such that it points towards the front of the coach. It is routed over the engine and the end of the tube is just about over where the engine and transmission are joined together. This causes blow by to flow down both sides of that area and form a film just near the inspection hole that allows techs to see the rear engine seal. Early on it caused a rookie tech at a local shop to diagnose a leaking rear engine seal incorrectly. A second opinion from a more savvy tech at that shop and then again at the Spartan factory both say there is not a leak they can see. BTW, for the first 6 months I had it, it was stored indoors on a concrete floor and there was no evidence of leaking so I don't think there was a rear seal problem either.

Based on the input I may decide to re-route the tube or put an extension on it to lengthen it beyond the housings and point more directly towards the ground.
