TruXedo & BedRug

LoPro & BedRug Mat

Bryan McQueen

Google Review on June 5, 2019

I purchased a TruXedo tonneau cover and a Bedrug mat from Rock Bottom Truck on Friday, 5/31/19. I had never heard of them before. I inquired about a tracking number for both packages on Monday, 6/3/19 late in the afternoon. Zac from Rock Bottom Truck responded the next morning with the tracking numbers. He was very friendly. One item arrived yesterday (Tuesday, 6/2/19) and the other today (Wednesday, 6/5/19). It only took 4-5 days for both items to be at my doorstep. Both packages were exactly as described and in great condition (See attached photo). He even followed up after delivery to offer any help/advice on the install. I give Rock Bottom 5 stars for great friendly service, FAST shipping, and quality of packages upon arrival. I highly recommend ROCK BOTTOM TRUCK!

Yakima

HangOver 4

Marisol Wong

Google Review On October 13, 2020

Love our new bike rack- Yakima hangover 4. When looking for a new bike rack to accommodate more than 2 bike I wanted something that would not extend really far from our tailgate (Tundra Truck w/ 2in receiver hitch). Found Yakima 4 had mixed reviews (the not so good ones were mainly from people who didn't realize its for bikes with fork suspension) and most places it was really expensive $600 before taxes. Our family has all mountain bikes with full/or front suspension so was perfect for what we were looking for. Ordering and receiving the item was fairly quick, it arrived in under a week and we love it. It's well made, sturdy and looks Great too!!!"

Order a exhaust system for truck fast shipping and everything there. Plus lowest price around. Can't wait to install this weekend. Great service all around I emailed them asking for shipping information and within an hour had tracking number. And exhaust showed up 2 days later. Thank you.

WARN Industries

Elite Series Bumper

Ramses Montes

Google Review on August 5, 2020

I had no Idea these guys existed. I stumbled upon them by chance and I ended up getting an amazing price (way better that the big distributors out there) and top-notch customer service with a super low response time. Unfortunately my package got lost by UPS but Zac took care of filing the claim and well as shipping me a new item. No questions asked. RockBottomTruck does an amazing with their great customer service, prices and inventory. I know that I will come back for my part needs over and over without hesitation and you should too! Thanks Zac to Zac and the RockBottomTruck team!!

Exactly what I was looking for at a price that couldn't be beat. And the stars must have been in alignment because it was delivered in ~24 hours (Amazon can't hardly do that).
