Ouch! I'm so sorry, Gwen. If you've gone through these forums, you'll know that my 1707T, bought new, suffered tire failure after less than 5000 miles due to tire cord separation on both tires. Fortunately, my tires did not blow, and a following motorist alerted me to the problem (he could see a tire smoking), so I didn't have the damage you had.
I know the OEM tires on our trailers are not really strong enough, so my first "fix" was to upgrade to Load Range D tires. But, I also had my axle moved forward about 3" and a 1 1/2" spacer put in to raise the trailer above the axle more. With that modification, I was able to install bigger rims and tires, so now that running gear is much safer.
Just so you'll know, the OEM tires on your trailer were the same as mine - 205/75-15R Load Range C as I recall, and they had a combined gross weight rating of 3500#. Your trailer is slightly larger than mine and my trailer has a maximum gross weight of 3800#! My new tires and wheels have a combined gross weight rating of about 5000#.
My other addition was to install a GOOD Tire Pressure Monitoring System (TPMS), from Minder Research, that monitors both the tire pressure AND its temperature. A tire that is headed for a blowout is normally heating up quite a bit, so with that system, I have some early warning.
Gwen, my guess is, if you are a bit of a "do it yourselfer", you could fix MOST of the damage caused by the blowout. If you did, it would not be too expensive. And, if you wanted to move the axle like I did, that was not too bad either. I had it done in a welding shop in Tucson for $400.
So, I know all this "advice" is a bit late, but keep it in mind if you decide to get your trailer running again.
