    I have some rust under the drop in liner on my '07 DC.

    When I bring the truck in for Bilstein 6112's, I plan to have the shop take a look at the rust (one hole about grapefruit sized, as far as I can see from underneath, maybe there's more).

    Despite living in the salty northeast, I don't plan on taking the truck out on winter roads...will just take the '09 Highlander when it's like that, since in winter months the plow will be mounted and it will pretty much only be used for plowing the driveway.

    Anyway, let's say I get the rust repaired by the shop.

    then have a spray in liner installed.
    '
    Is there any reason to not reinstall the drop in liner?

    Is the bed's interior now pretty much rust proof with the Linex?

    Can I just skip the Linex and reinstall the drop in liner, knowing that I am not going to be out on the salty winter roads?

    Thanks for the advice in advance...

    I'm curious what others think about this. I wouldn't do both a spray in and a drop in liner. Since you already have the drop in liner and aren't going to drive it in the winter, that's probably a decent option but is it possible for water to get below the drop in and rust your bed anyway?

    The drop ins are only nice for shoveling stuff out of the bed. Other than that they are too slick imo to haul things around

    For my use, I kind of like the drop in liner.

    Just don't want to go to the expense of fixing the bed and risk having the rust happen again.

    then again, maybe the return of the rust is not an issue with limited on road winter usage?

    But, if I get it Linex'd, that's $500 maybe I don't have to (or want to) spend, and if I don't re-use the drop in liner then I have to figure out how to get rid of it.

    You run the risk of it happening again if you fix the bed and then throw the drop in back in on top of it. With or without salt, it’s in an area that will trap moisture. I suggest you look from underneath as well, check all the cross bracing where the bed meets the braces. Sometimes they rust from the bottom up even though it looks like it started in the bed. So even if you get it fixed and have it lined, it’s possible rust could come back. The lining does help protect it but if it’s coming from all directions, now you have the liner to contend with to repair again.

    Since you do like the drop in, I vote option number 3. Fix the bed and then do a DIY liner after prepping all the surfaces really well. Then throw your drop in on top of that.That should save you money and give you the best of both worlds that you’re looking for.

    I would go with just a bed mat. Easy to install, much cheaper than a spray in liner, easy to remove for cleaning under it, holds stuff in place very well, doesn't rub on the paint like a drop in liner, etc.

    I'd say do whatever you like as the bed rust on Tundras starts from the underside of the bed not from the top.
    If you do a search you'll find many threads on this issue.

    Definitely aware, and have read many if not all of the threads.

    I'm pretty sure mine started from underneath.

    It does seem to be in the "not too bad" rust category frame wise etc.

    The thing is, I really love this truck, and would like to get it fixed the right way.

    Do I wish I had $50k to buy one new? Of course.

    But for what I spent ($17k), and the fact that, now retired, I will be putting a limited number of miles on this thing, I am hoping it will last a long, long time.
