Big Bertha came with Absorbent Glass Mat (AGM) lead acid batteries when we bought her in 2018 and we replaced these with another set of AGMs in Namibia in 2022. They have served us well. Lead acid batteries are very robust but have two inherent disadvantages in our application: Lithium Iron Phosphate (LFP) batteries do not have these disadvantages; they […]
We left Oaxaca and headed towards Tehuacán. All started out well, but Big Bertha steadily lost power and progressively exhausted more and more thick black smoke. By the time we reached Tehuacán we were having trouble exceeding 40kph and climbing hills. All was definitely not well. We found a wild camp and the next day Dave started diagnosis with the […]
We last treated Big Bertha to new tyres in Johannesburg, South Africa, in September 2022. We have covered 62,587km since then and we were running almost on F1 racing slicks. Our wheels have 20 inch rims, which are almost unheard of in the Americas and we use military tyres – so it’s not a case of pulling into the nearest […]
People (well, Jo!) have asked us for a tour inside Big Bertha. We have gone one step further and we have a short video (30 minutes) detailing Big Bertha. We hope you enjoy!
Exploring Copacabana in Bolivia, we saw a lot of decorated cars around the town. Further investigation revealed they had been adorned with trimmings in preparation for their blessing by the pastor at the town’s church. Turns out this is quite a thing. Each day at 10am and 2:30pm, and especially at weekends, vehicles assemble outside the church ready for their […]
Sometimes our posts make it look like our lives are exciting and extraordinary, but it isn’t always sunshine and roses, so I thought I would bring it all down to earth a bit.. Today was not a good day, mechanically-speaking! We had overnighted in a typical “panoramic-view” type of spot, with no-one around – just us and the stars. But, […]
The highest settlement in the UK is Flash, Staffordshire, at 463 m (1,519 ft) and the highest point in the UK is Ben Nevis at 1,343m (4,406 ft). The northern parts of Chile, Argentina and southern Bolivia are a lot higher and it was time to test our ability to travel at altitude. From the Chilean coast we climbed steadily, […]
And I’m still rolling along –The Cherokees are chasing meArrows flyRight on byBut I’m singing a happy song! Big Bertha broke down on a ripio (corrugated) road in Argentina in July 2024 and having made a temporary repair, we toured northern Argentina waiting for replacement parts to come from Germany. Six weeks after our order, they were finally ready for […]
There we were, driving merrily along a ‘ripio’ dirt track from the Salinas Grandes salt pan to San Antonio de los Cobres, in the middle of nowhere, when there was an almighty noise from underneath Big Bertha. We stopped quickly, expecting a puncture. But no, it was something much worse, the front propshaft, along with the transfer case output shaft, […]
Our new Starlink has been a bit of a game changer for us – internet everywhere. Pricey, but worth it. However, setting it up and putting it away each time we want to use it is a bit of a pain. So Dave researched what other overlanders had done, ordered parts whilst in the UK and, whilst stranded at the […]
