I’m sure this has been asked a million times. Is it ok to use ripped 2x4’s for under floor framing/ sills, or is there a better choice? I can’t seem to find Poplar “2” by anything. Or hardwood for that matter. Will pine hold up ok over the next 60 years? I can’t tell what type of wood they used when it was built, but it doesn’t look like pine to me.

Douglas fir is harder and can be found as a 2 x 4 but it’s not cheap. I have used both Douglasfir and pine. The problem with pine from A big box store is it's soft. Will do the job? Yes. Will the last 60 years? I doubt it.

Check at saw mills in your area. Sometimes they will have different types of wood. Not at the big box stores. Debra

One other thought, it may be a good idea to coat the pine 2x4s. vikx has recommended fence post paint but even an oil based house primer & paint would be better than nothing. I've used Rust-Oleum Hammered with good results.
If you live in the desert you probably will be fine without it. |

I have purchased POR for frame already as well as black beauty for the the underfloor/sound board. I was under the impression that you should not paint wood so it would dry out if it gets wet. But maybe I was wrong. I live in northern Indiana, it’s almost as bad as the Pacific Northwest for rain, at least it seems like it anyway.

Campers I’ve owned came from the factory with some sort of thin sealer on framing. I usually follow the original building techniques. Although I’ve heard before not to paint framing.
If I lived in a very wet climate with rough winters and every time I took the camper out it was going to be splattered with water and road waste, I would seal or treat framing. Others may disagree.

Thunderbirdlindy, it's always a good idea to paint wood that's to be used exposed to the elements. What you heard was probably regarding treated material (c.c.a.) and such. From the treating process of being soaked it has so much moisture in it, it is recommended to wait a long time before painting or staining. Either one will just slough off.

Thanks for the feed back, I called around and I am going to use #1 yellow pine for under floor framing. I did a little research, never knew there were so many different types of pine and hardness factors. I will also paint it with black beauty paint even though it will be sandwiched between floor and sound board.

Consider 2X4 cedar for its weather resistance. It is used for decking and fences for that reason.

The same is true for a lot of tree species........ Debra |

Douglas fir is one of the hardest. I bought some rough cut and had it planed. I have a table saw and can rip and crosscut lengths. Worked very well
