Manufactured homes are built with the same materials as site built homes. They are held to building codes the same way that site built homes. The main difference between the two building methods is that 80% of the building process for manufactured homes is in a climate controlled factory.
Broil 5-8 minutes on each side to desired doneness. Mix all but steak together. Place round steak and marinade in a plastic bag or glass container and let sit in refrigerator for about 3 hours. Turn container several times. Broil 5-8 minutes on each side to desired doneness.
Put the steak in a resealable plastic bag. Pour in 3/4 of the marinade and seal the bag. (Reserve the remaining marinade for the bread.) Let the steak marinate at room temperature for at least 30 minutes. Put the peppers and onions on the grill. Coat the onions with BBQ sauce. Once the peppers and onions are charred, move them to the top rack to keep them warm. Remove the steak from the marinade and put on the grill. After 5 minutes turn the steak over to sear the other side, about 12 minutes total cooking time, for medium-rare. Transfer the steak to a cutting board and let rest for 10 minutes before slicing. Cut the bread lengthwise and toast on the grill. Brush the remaining reserved marinade on both sides of the bread. Arrange the steak on the bottom half of the bread, then cover with the peppers and onions. Top with the cheese and cover with the other half of the bread. Cut into 4 pieces and serve.
