The only problem I've heard about is the crack in the I-40 bridge over the Mississippi. It's not an issue if you go over the I-55 bridge which is just a bit further south. Then connect to the wrap-around Memphis if you are going East. If you are going west hit the wrap-around on the east side of Memphis and follow signs to the I-55 bridge and connect with I-40 W. in Arkansas.
We have a trip planned this fall and I've already preplanned to take the route around the I-40 bridge even if they have the repairs completed by then. That's really the only option unless you wish to go much further south to West Helena, AR and go over that bridge to get into Mississippi and then head north to TN. However that is really out of the way.
We have this Giantex washer and find that it works very well. Clothes come out dry enough that hanging the on hangers in the shower will have them dry by the next morning or we have a retractable clothesline that we also sometimes use.
