Hi John and Vicky. Welcome.
Both brands are excellent.
Bigfoot is built in British Columbia thus the western presence.
Oliver is Tennessee. Closer to you.
I have a
Bigfoot and for me, as a Canadian, I am loyal to Bigfoot. That said,
Oliver look to be excellent quality.
You are right, for any warranty service, it is good to be positioned closer to the factory. That said, these brands are not built like regular RVs.
Most of the stuff out of Indiana is pretty much good looking but not built for the long haul. A lot are vacubond walls which can soak up water pretty well. Big issue.
Fiberglass unit’s like Bigfoot and Oliver are constructed like boats. Water doesn’t touch them as long as you keep up with the sealants - sealants make the seal between parts and covering screws etc. No sealant means water entry!
You need to calculate your tow vehicle accordingly so do your homework.
