Potential issues leaving bleach sanitizing mix in the lines for several days?

We're two weeks out from our next camping trip, the campers' been sitting in the storage lot for a couple weeks (and the weather's gone between hot and humid to LOTS of rain in a short amount of time to cooler and drier.)  The fresh tank / hot water tank / cold water lines were all drained before storage.

I'm thinking of going out to our camper this weekend and, if it won't potentially damage the lines / tank, suck in a sanitizing solution (1/2 cup bleach in a 1gal just, then fill tank the rest of the way with fresh, run water into all lines) to save a little time when we start preparing the camper for our trip.  Figure the solution would be in the system for a couple days, say Sunday to Wednesday evening / Thursday sometime.

I'm not an expert but you need to by-pass the hot-water tank for sure. Perhaps the bleach is diluted enough, but it's not good for PVC (pipes) to have bleach (Clorox in particular) sitting in them for that long.

@Slackers and that's why I'm glad I asked before going through with my plan!  We do know to keep the sanitize solution out of the hot-water tank, I hadn't thought about (or, honestly, knew about) bleach and PVC not getting along, so that's a very good to know.

Guess we'll be putting the sanitize solution in the day we bring the camper home and flushing it out after an hour or so, as usual.

Thank you!

I've sanitized for days.  You'll be fine with a dilute solution.

Codes requires sanitize and flush of all new lines, pex or otherwise, in all structures and underground lines.  Something Nucamp does not do based on the ubiquitous pex cutting debris found in everyone's water pump strainer.

I also sanitize the hot water tank. The hot tank water usually won't get hot enough on it's own and can contaminate the rest of the system before it's heated. A diluted solution should be run through every hot/cold line, tank, faucet, and drain including out the low point drains and the yellow flapper valve. After it sets for a while I drain and refill with water until it comes out the overflow drain and flush everything again.

Just don't leave the bleach solution in the hot water tank for days.  Hours only.  Chlorine causes pitting corrosion in stainless steel.
