Under trailer storage tubes

So in my smaller trailer, 2015 Creek Side 20fq, I am struggling to get everything situated. I didn't have a good place for my lawn (astro-turf) so I decided to go the rout of putting a 6" conduit across the trailer that has the "kit" installed with cap on the end and a latchable-lockable door on the access end. Then I got the bright idea to put the collapse-able chairs in an 8" version. So I have everything set up and started looking at how low that dude hangs. It's not as low as the axles, but hmmmmmmm. My trailer is pretty high with the offroad type chassis and I am sure just buzzing down the highway everything would be fine. Occasionally we take a jaunt off the pavement aways, but we never really go off-roading like real tight twisty ups and downs.
Wondering if anyone has strapped something like this under their rig and what your luck has been...........

Thanks,
