Best SUV for High Monthly Running (2000+ km) - Need Efficiency Advice

I'm planning some major camping trips next year and need a capable SUV that can handle everything. Looking for something that won't struggle on rough terrain, can carry my mountain bikes on top, and has space for camping gear. Budget is flexible up to ₹15 lakh. I've narrowed it down to these four, but torn between the Thar's capability and Duster's practicality. What would you choose for serious adventure use?

I recently test drove a friend's old Duster and was impressed by how solid it felt compared to newer cars. With the new Duster coming soon, I'm curious how it'll stack up against today's safety-focused SUVs. Looking for opinions on which SUV in this price range feels the most robust and secure - especially important given our road conditions and highway speeds.

I frequently travel between Mumbai's corporate hubs and construction sites in Maharashtra's rural areas. Need an SUV that looks professional for client meetings but won't struggle on rough patches and village roads. Budget isn't the main concern, but reliability and ground clearance are crucial. Currently comparing these options - what's your take on the best all-rounder?
