your original question is "Are Time Consuming Conversions a MISTAKE"
well, it's all relevant (as much as the rigs themselves are), as to what 'time consuming' means to each individual, and at what point the conversion time becomes a mistake.
Me personally??? I've built all kinds of rigs. Everything from basic van conversions and simple RV mods, to full on complete hot-rod builds, and choppers where I had to build absolutely everything, from the frames on up. My latest hot-rod truck project I've been building for nearly 7 years now....YES...
7!!! I also designed and built my own custom home too. I see alot of folks on here who modify their rigs because they can't stand the way the original builder or manufacturer designed it from the begining. I understand this mindset, and I am NOT someone you'll meet driving a storebought van. Everything I've got I've customized in one way or another
But...you see, I get alot of enjoyment from building my custom things, so in my eyes, taking a long time to do a build is something I don't necessarily mind. It's not a "mistake".
Some folks find hanging a single shelf on a wall a big challenge, and the thought of framing, building, wiring and plumbing a small van into a conversion/dwelling is a unbelievably daunting proposition. They have no idea where to start, or how to proceed. The tools are unfamiliar, nor do they have any idea of how to use 'em.
heck...I've been at this game for over 30 years now, and I'm still learning about new tools, fasteners, and techniques I've never even considered before. (It's funny how tools or tricks can merge from one industry to another.) I love learning new stuff like this.
Look at the volume of questions this forum gets about solar panels. There's ALOT to learn if you have no idea of where to start or how to proceed...especially considering the initial investment of materials. Most everybody wants to learn as much as they can in order to make the best educated purchases to fit their individual needs and applications.
lastly, a person who's recently lost their living space, has little savings, and has few alternatives, will find that building a van while trying to live in it, while maintaining a job, will constitute a phoenominal difference from the retired fellow, who has a nicely set-up shop and all the time & money in the world to do a quality build with lots of very nice features in it.
is the more elablorate build a mistake over the quick one??
not if you're enjoying the process.
Y'all Have Great Week!!!
