Like all choices, it needs to be a compromise. I have no experience of either of these units.
The Clarke only has domestic 13 A sockets, the Towsure has Blue sockets, so it depends if it is likely to get a rain shower.
The Clarke has 7 hours running, the towsure is half this.
The Clarke can charge 12 volt batteries, the towsure can't.
Either way you will need to padlock it down.
I have a Briggs and Stratton powered generator, with the alternator bolted on the end.
Very simple, but with a 1500 watt output, doesn't power the power washer, but is happy with the Vax and all my power tools.
It is very noisy, but also has 110 volts output (never used).
It does hunt especially on low load, but in the event of a home power cut, it easily copes with the heating, TV, computers, but doesn't like the inductive load of the fridge or freezer.
So choice is down to application.
Certainly a sine wave generator is the best type of inverter, as normal inverters are actually square wave, and produce harmonics ( ie high frequency electrical noise), that can damage some sensitive electronic equipment.
You also need to decide where it will be stored while in transit and use.
Also you will need an earth rod and RCD device to help protect the system and people.
On my boat I link into shore power, as I already have an RCD and circuit trips in place. Also the option of using my 800 Watt inverter.
Hope this helps.
