Rather like being PG, either you are or you're not. Interesting concept, they should patent it if possible then sell to Scepter or RotoPax who are familiar with fuel safe materials. That would put me onboard. :)
Nice mods. I'd be a little leary of the ac chord between bumper and body as there can be significant movement there. perhaps something like this?
Not to prolong this thread but isn't the very nature of off/roading- overlanding portable? The units that use bottles to a small hard tube are the exception. I'm glad that you pointed out the lined lines and I will endeavor to locate some. Thanks.
This issue is probably more common than we know. Mr Buddy heaters highly suggest using a filter as close to the unit as possible, you may want to investigate? Getting your tank purged and cleaned couldn't hurt.
