RODENTS!

If they’re known to be present, a couple rat traps with peanut butter are pretty deadly in my experience.
Couple summers ago, my field engineer, living on our Jobsite in a camper in the mtns, got 30-40 of those suckers over a few months, no chewing on the camper was done!

Can’t leave the hood up on a TT!

Rodent tape seems like a good idea for known or suspected tasty spots too. Never heard of that stuff before.

leaving the hood open works because the rats don't like the light. They want their nest to be dark 24/7. Google Rid-a-rat, it's a small LED strobe that you hook to your battery and should keep the packrats away. Don't know if it works on mice though.

If you store it where you have power, keep a radio playing inside it. I’m not sure if it will keep them out from under the hood, but it works for my garage. I keep a radio on constant and have never had mice even though there are gaps at the overhead door where they could enter.

Anti Rat Pro Spray is good for keeping rats and mice away and keeps them from chewing up wiring and hoses. It is a hot pepper based product that spices up rodents lives and keeps them away.

Some bird seed products have ground red pepper added to it to keep squirrels from getting into it. Birds are immune to the spicy heat of hot peppers so it doesn't bother them.

The spray can be used on vehicle hoses and wires to keep rodents from chewing them up. It is also sprayed around under the rig and in the engine compartment to ward off the unwanted wanted guests.

I know of a couple full time RV nomads that have had mice chewing on their wiring and getting up into their engine compartments that swear by the spray. They also raise their hoods and place a light under the engine compartment at night.

and on our daughters ford edge that was atracting rodents we used the honda rodent tape. One of the best $40 we spent.

We have several campgrounds where as soon as you park, up goes the hood. Alternative is in come the packrats and start chewing on wiring.

I guess for $2500 to $3000 I'll find other ways.

Google Honda rodent tape. This is Honda's fix for the soy based wiring insulation they started using a few years back. No reason you couldn't wrap your fuel lines with it.
