If you have laid out the heavy investment required for the full T/M set up I don't think you.re likely to admit that you might have regrets.
I have trialled T/Ms and weighed up the pros and cons before coming to the conclusion that, you need to target the market ,to suit the machine, which I'd regard as very restrictive and compromising.
To overcome this situation, you will require to have a portable, or restrict your activities.
Also, the setting up / clearing away time for portables is considerably less and the ability to park at the location virtually every time is a major bonus.
The concept of having a powerful portable which can be either left in the van, or takin closer, when necessary has to be the most attractive option.
When I did this I used a CFR , BUT THERE ARE NOW SEVERAL EQUALLY POWERFUL PORTABLES AVAILABLE.
Also, there is the option of ' auto fill ' and ' auto empty ' making the portables even more attractive.
However, at the end of the day , it's personal choice and we will never all agree, on chemicals, cleaning methods or anything else..............
ahappy days
