Hi there
@Headingoutdoors and welcome to the forum. There are many experts on this forum as I found out in explaining the parts involved in my "simplistic terminology of the ignorant". Promptly and correctly put in my place by
@Drover, but even he saw it as somewhat different to his usual thinking.
However, as
@Drover has the 'know how" and the ability to do these things himself, he was way ahead of me at first. If you look under the heading of "Suspension - off set axle banter" thread, you will find lots of posts and pictures of what an under slung axle looks like and its benefits. Even though
@mikerezny and I both have Penguins of 2013 and 2016 vintages (mine is the 2013), you can see that there was a difference in original axle position.
@Drover is correct in saying that I have at least 50mm greater height (clearance) than original, I believe it is more like 90mm because of the extra step I now have to use to climb in and out of my van. Have a look at the pictures and gauge for yourself. A great advantage in most areas as explained by
@Drover , so can recommend such mod. No change in towing or handling ability, but be aware that your hitch point on draw bar will now be higher (I reversed the ball position on mine!!) and also your awning or other things you hang on the outside will be a little shorter to the ground and may be of consequence. Something to think about anyway. I think the ball park figure to have the axle under slung was approx $300 to $350.00 at Brendale.
I hope this gives you a bit more information, but as I said have a look under Suspension Posts # 1 (25/1/18) to # 29 (6/2/18) for all the info you need. Good luck!! Found some photos for you too.
