In this episode, we dig into two big questions RVers love to debate: should you really be using a diesel fuel additive, and where should RVers be allowed to park overnight?

First, we talk about a public library in Maine that found itself unexpectedly listed as an overnight camping spot on iOverlander. That leads us into a bigger conversation about free overnight parking, responsible boondocking, the “freeloader” label, and whether more towns should be creating low-cost or free spaces for RV travelers instead of simply putting up “No Camping” signs.

Then, we’re joined by fuel chemist Jessica Crabtree from Power Service to break down what diesel additives actually do. We talk cetane, lubricity, CP4 fuel pump failures, cold-weather gelling, biodiesel, water and microbial growth, injector deposits, and why the diesel coming out of the pump may not always be ideal for modern engines.

Plus, we talk about Winnebago’s latest production cuts, a new RV tailgating experience at Soldier Field, the increasingly frustrating state of package delivery, and a whole lot more.
