"Now per my recent title experience:
If the trailer is declared " Home Made, Non-titled" and its GVW is 4,000. pounds or less, you do NOT need to title it in Texas. You still need to REGISTER it. Big difference. You get a plate all the same, but no Blue Title."
Home made OR manufactured, if below (maybe up to and including) 4000# GVWR, no requirement for title.
I can't seem to find DMV trailer info right now but I'm Peaking at Twins and not gonna put any more effort into it.
Federal law. I have never heard of this, but other than BLM / National Forrest land how would the federal government have any jurisdiction over our off road toys?
