I installed two of the cup holder units with my underfloor package, with the RV storage solutions false floor replacement above. It was a relatively smooth process, took a while even as a tradesman, but nothing difficult. It all fits in well, and the quality and finish is immaculate. I would gladly purchase it again, and if someone is tossing up on it, I'd say it's worthit personally.
Great kit, easy to install!

Accelerate did a very good job of installing an Evacool 40 L fridge and a drawer stacker combination into my Prado Altitude. Under the floor is a 100ah ITech lithium battery and Redarc bcdc 25 amp core charger I also added a Victron 25 amp AC/DC charger and a brushless twin ARB compressor. ( would have liked it in side panel) Very Happy with the quality and workmanship of my setup

Really happy with the simple install and quality components supplied. One happy camper :)
Fantastic kit! We installed this after suggesting it to a customer who was wanting a second battery installed on his new Prado 250, and it couldn't have been easier! Instructions were simple to follow, kit fit like a glove and the build is spot on for quality! We'll be recommending this to more customers!

My Prado is still on order.At this stage i have no idea when it will arrive to fit the dual battery system.
Couldn’t ask for an easier package to connect, everything worked perfectly and hides neatly under the false floor! Will recommend to anyone who listens

Store owner replied: Thanks Wade. Stoked you're happy with it
Hi Guys, I fitted the under floor kit to my 250 Prado. A couple of issues I had: 1. The board did not quite fit so I had to drill a new hole to get the bracket right. 2. The cup holder hole wasn't quite big enough to allow the wiring etc to sit properly so I had to drill that out a bit more but it doesn't sit as flush as it did in the video. 3. We purchased another 100aH battery which did not suit the existing holes in the board. The supplied wiring to the battery therefor didn't suit either so we had to buy a little extension and bolt that together to connect to the battery. Otherwise, it looks great, works really well and has had my fridge powering really well. It is running a 70L Dometic. We ended up bolting the fridge slide to the steel frame as I have the 5 seater - people who have the & seaters will have to a false floor I imagine as they don't have the steel frame to bolt into. Love the bluetooth battery connection so you can see where it is chareged etc. So in general, I'm really happy with it, thank you!

The parcel arrived open and all over the place, it was sent to the wrong address and it took me over a week to find the battery which turned up in Dubbo. So not a good start. Now that I finally have everything where its should be I can now install it.

GREAT PRODUCT
Waiting for my Prado Could be Xmas
I didn’t actually fit the system but an electrician did and he was impressed with how it all went together. We have a faulse floor fitted to the car and there was only one cross member that needed to be trimmed for everything to fit.
