Spot,

I just sold my T100 (bought a Silverado Crew 1500) and I am installing an ARE MX Series topper with the "side win-doors" you are talking about. My truck has the extra short 5'8" bed so I also want this for easy side access from the topper and to preserve the limited depth of the bed.

I have researched everywhere and found nothing. If you find anything please let me know. Otherwise, I'll have to go with a custom "el cheapo" wood box option over the wheel well.

Thanks,
Candido
