Thumper portable battery is the way I've gone, no regrets

ol coot
I have a v6 Rav 4 and an 1991 v6 4 Runner. neither have room under the bonnet for a 2 nd battery. I use a Waeco 36amp power pak in the back of the vehicle. This is charged using an engel 10 amp charger which only charges when the engine is running. As I have a 36 amp hr pak in each vehicle if I am going away for a long period of time I take both batteries and link them together. I have a Waeco 40 fridge, an Evercool 40 and an Engel 40 and have never run out of battery power with any of the fridges. I use a 60watt Piranah solar panel to boost the batteries if we are not driving for a few days.
Hope this helps
Mike

I bought a Sidewinder battery box off Derek Bester. Replaced the plastic cover in the boot of the X-trail with half inch ply so i could anchor it down along with my fridge slide.
