Tarp pay question

We move over wide steel plate for a dedicated customer who is 150 miles away. There is a wishy washy tarp policy. The customer "prefers" all loads to be tarped, but has accepted a compromise where we do not tarp on sunny days when there's no salt on the roads. All loads pay the same, tarped or not.

I get $215 per load. 300 mile round trip, oversize banners and flags, sometimes tarped, sometimes not, and I'm thinking this is fair for untarped loads but a little light for tarped loads. What do you guys think. Is my barometer out of whack?

 

I'm considering making a little bit of a stink, because other accounts we have pay separately for tarping, this one does not for some reason.

But, would pushing for tarp pay open a can of worms that could jeopardize the entire account, or, end up with no change in pay but now 100% of loads are tarped just to put and end to my stink.

 

8 no tarp, 9 or 10 with tarp

 

I could too. But it comes up every year, it's not just me that scratches their head about the tarp situation. You can imagine if the pay is the same either way, sometimes guys don't tarp when they should.
