Curious, I see the 2x5 having greater strength the 'hard way', yet wouldn't the added height (without added thickness) make it more susceptible to bulging? 


Whups, I found a boo boo in my calc. I divided the moment of inertia by 2 for the 5 inch tube rather than 2.5. Correcting that I get an increase in section modulus of 39% not 74%. The 195 axle is rated at 4400 lbs so that's 26% higher than the smaller rpods. So there is still some headroom there but i don't know how far the rear of the trailer frame overhangs the axle which would be the other factor we'd need to take into account.  

A failure due to the walls of the tube bulging would be considered a buckling failure. Interesting question as to when a tall thin wall tube in bending would be subject to that. There are equations for bucking of slender columns in compression that I've looked at before but they're not really applicable here.  My gut feeling is that we aren't close to a buckling failure yet at 5 inches and 0.1 wall thickness, but I could be wrong.

Curious if I'm doing all this right.. I have 1.421 as the modulus for the 2x5x.1 frame

With all being said, what is the difference between the East Coast 179’s and the Hood River Edition (West Coast) height wise?? What does FR RPOD do differently to give the Hood River more ground clearance??

In  the early times, all they did was add an axle-riser; kind of a spacer between the axle and the frame. Later on (not sure what year, but our 2016/2017 model has this), they just "clocked" the torsion axle 10-15 degrees to raise the height.

I'm not sure, but I think the Hood River editions also have 15" tires instead of 14" on the east coast versions. this add a minimal amount(1/2"+/-) to the height/ground clearance.

That made me curious if any of the rPods now sold still have the 14" tires? My east coaster of 2017 is on 15".

My 2015 has 14", I think same year HREs had 15" and an off road style tire.
