Within the first few days of FL, I place about 5 ant traps thru out our Class C. Esp near the trash can. We also grease, using petroleum jelly, any cords coming in the camper. About a foot worth of cord @ entry. I do sweep my floor everyday, esp under the dinette. And keep my counters clear of food crumbs.
Never ever buy a Class C with that "useless front window" above the cab. A leak waiting to happen..speaking from experience. Since we don't sleep up there & the other 2 window are covered with reflectix..NO windows in over the cab area. Except for our Fantastic fan-<3 in the ceiling.
Several years back we took our C to a tractor & engine show in IL. RV parking was in an open, huge, field. We were just about the first ones there. The next day a C pulled in RIGHT beside us, about 3' back from our front wheels & when they pulled their awning out-about 2' away from the driver side of our C. We had planned to run the generator for a/c when it got too hot. We went over within minutes of them pulling in & told them they might want to have more space between us for we are going to run the generator. OH NO, it's just fine, your generator running will be just fine. A couple hours later, we asked them again to move away. OH NO, everything will be just fine. Ok, we ran the generator=their co2 alarm was going off, they're gone, we were given bad nasty looks when they saw us. WE apologized for the smell, good ole' generator noise & settin' off their alarm. Why, I don't know-we warned them. They said nothing. We left early. They were smoking their cigs & their smoke was coming in our dinette window. And the man must have had jock rot because he couldn't keep his hands out of his pants. I have since figured out they pulled in that way, cause they used our camper as their shade. :)
