Tire Blowout problems of the 2000 Ford E-350

Driving south on I-25 from albequerque to el paso. Tire blew out & I made a controlled stop. Looking under the rear inside dual wheel I saw the tire was shredded. I exited almost at once to a small town named belen, n. M. This occurred almost noon on a Saturday. I considered myself lucky to find a tire store open in such a small town. I'm almost 75 with a heart condition. No way I was going to attempt to change that tire on a hot interstate alone. Craig tire CO. Explained the recall policy. They replaced the blown tire (in 2 pieces) and placed it in my RV motor home. I paid them $165. 08 and have the receipt. I was lucky to have found a tire dealer on Saturday in the middle of the new mexico desert. I have called Ford, firestone, the RV dealer, the RV manufacturer, the local tv station, even the newspaper. I understand there have been many complaints. Thank god no one was injured or killed. Thence, news of no importance! wrong! I'm retired. Unexpectingly I purchased this vehicle to travel at my leisure. The price of almost $69,000. 00 is not primarily important. Someone selling me something that could have ended my wife's and my lives is my major concern. How many other unexpecting buyers may not be as fortunate? I used to drive a semi; I owned 12 trucks. Good thing I had experience with blowouts. Perhaps the next person won't know how to handle the blowout. Luckily, this was not a front tire, but an inside dual rear tire. I don't want the firestone I have. No one is interested in my problem nor reimbursement. Additiionally, on closer examination I found another tire, same size, on the right rear outside dual has a 2" crack in the sidewall, which I deem unsafe to drive on. I also own a 1998 Ford ranger equipped with firestone wilderness ht tires, p225/70r15 m/s 1005. This vehicle has only 5,281 miles, purchased new. I'm told wildreness ht's are not included in the recall. I would appreciate your clarification. (dot number: vd1l 1xd tiresize: 225/75r16e).
