Howdy and welcome to the forum!
Using angle iron to support a saggy underbelly is a good idea, as the RV industry doesn't seem to know how to properly support the holding tanks or freshwater tank.
As Roadglide stated, it would be a good idea to verify the sag is not caused by water retention, then install the new support.
Have fun and take care!
