I did the truck conversion with zero experience and it's been a huge pain but it's finally coming together. I bought myself a welder and all the supplies, which was about $1500. Then quickly realized I was in over my head and have paid another $1000 or so in having local welders from Craigslist help me troubleshoot some things for about $60/hour. Now I need to buy rhino liner and have it painted.
This is going to be a $3,000 job at least but if you had someone do it for you it's time intensive and I had 1 auto welder tell me it's ballpark $15,000 conversion to have someone else do it. Besides all the headaches it's been a fun project though. Helps when you have a motorcycle to ride in the meantime. I ride a SFV650.
