More Marathon blowouts

We have had three blowouts, left side, on our '08 model 3124 KS... in the last two cases, the blowout has ripped out the sewer plumbing behind the tire. In one case, the floor cracked, and the toilet cracked, from the blowout shards...

Last night, we had the third blowout, and again the sewer plumbing is destroyed... this is first camping trip since last blowout last summer... 55 - 60 MPH, interstate 95 in NC, 92 degrees. Tires at 62 PSI... towed by 2008 GMC Acadia, factory tow bar...

I have yet to call TrailManor factory...

WARNING: The 3124KS is "under-tired," or needs a second axle, or needs larger tires!

We are sick, and disgusted with TrailManor quality... willing to discuss here.
