Good advice. One of the things Subaru did (big time) in the series I SG was to strengthen the frame. Did more of this in the series II SG, and more again in the SH.
Weight distribution and amount is one reason why trailer touring can be a better bet. That load is carried on the trailer axle (usually far stronger than the car stub axles - mine is rated at around 2 tonnes, IIRC, and the trailer can only legally weigh 750 Kgs all up). The trailer wheel bearings are also far stronger than the car bearings. So are the trailer springs. The springs on my trailer are "light weight", but are still rated at around 600 Kgs each!
The GVM for my SG II is only 1950 Kgs total, with a maximum of 1035 Kgs of that on the back axle when towing a trailer. Maximum ball weight for my car is 75 Kgs. I will try to keep that at around 40-50 Kgs.
As the unladen car weighs 1380 Kgs, it indicates a maximum added load of about 550 Kgs. Two people at 75 Kgs each is 150 Kgs of that. Each 20L steel Jerry can weighs about 21 Kgs ... etc.
Single axle trailers are generally very light, and even with a trailer tent fitted they have very little effect on the driving characteristics of the car. My 7x4 trailer with a steel lid and 6x4 trailer tent that is bigger than some bed sit flats I have been in when set up, still only weighs around 300 Kgs. Add in 60 Kgs for extra fuel and water, another 20 Kgs for gas bottles, around 100 Kgs for other crap (like my spares, tools, creeper winch, compressor, roof rack - yes, it normally travels in my trailer, not on the roof bars!), and the whole lot is still only around 500 Kgs.
Don't even notice it being there most of the time! Sure takes a lot of load off the car's springs and frame. With any box trailer, there is almost zero drag as long as it isn't empty. When empty, they act like a parachute behind the car unless one removes the rear gate ... :iconwink:.
