IMHO, Frazier realized how long the bag was and intuited that it contained a broken-down rifle, but lied about it later because he was afraid he might incriminate himself as an accessory to the murder of the President of the United States if he told the truth.
I think you're probably right, a package that was about "2 feet long, give and take a few inches" could easily be kept comfortably with you in the front seat and especially if it was Oswald's lunch like he says, but regardless, Oswald first goes beyond where he later waited and went straight to Frazier's car, opens the back door up and immediately hides the package in the car on the back seat. If indeed it was relatively light curtain rods, wouldn't anyone else just keep the package on their person till Frazier came out? instead of hiding the evidence as quickly as possible!
Also what's pretty funny is that in the first photo below it's claimed by some extreme Ct's that Linnie Mae couldn't see through the open slats to see Oswald, Hilarious!


Linnie Mae Randall told the FBI on the day after that the package was approximately three feet long.
RANDLE stated that about 7:15 a.m., November 22, 1963, she looked out of a window of her residence and observed LEE HARVEY OSWALD walking up her driveway and saw him put a long brown package, approximately 3 feet by 6 inches, in the back seat area of WESLEY FRAZIER's 1954 black Chevrolet four door automobile. Thereafter, she observed OSWALD walk to the front, or entrance area, of her residence where he waited for FRAZIER to come out of the house and give him a ride to work.Frazier says the package was around
"two feet, give and take a few inches."Mr. BALL - From the side of the seat over to the center, is that the way you would measure it?
Mr. FRAZIER - If, if you were going to measure it that way from the end of the seat over toward the center, right. But I say like I said I just roughly estimate and that would be around two feet, give and take a few inches.
Mr. BALL - How wide was the package?
Mr. FRAZIER - Well, I would say the package was about that wide.
Mr. BALL - How wide would you say that would be?
Mr. FRAZIER - Oh, say, around 5 inches, something like that. 5, 6 inches or there. I don't--And Linnie in her testimony folds a sample bag and the length was 28 and a half inches then she quickly corrects this guess by saying another sample bag was 27 when it was measured once before, she was trying her best to shrink the bag. Which was most likely after she colluded with her brother to keep Oswald's rifle sack as small as reasonably possible.
Mrs. RANDLE. There again you have the problem of all this down here. It was folded down, of course, if you would take it from the bottom--
Mr. BALL. Fold it to about the size that you think it might be.
Mrs. RANDLE. This is the bottom here, right. This is the bottom, this part down here.
Mr. BALL. I believe so, but I am not sure. But let's say it is.
Mrs. RANDLE. And this goes this way, right? Do you want me to hold it?
Mr. BALL. Yes.
Mrs. RANDLE. About this.
Mr. BALL. Is that about right? That is 28 1/2 inches.
Mrs. RANDLE. I measured 27 last time.
Mr. BALL. You measured 27 once before?
Mrs. RANDLE. Yes, sir.Mr. BALL - All right.
When you got in the car did you say anything to him or did he say anything to you?
Mr. FRAZIER - Let's see, when I got in the car I have a kind of habit of glancing over my shoulder and so at that time I noticed there was a package laying on the back seat, I didn't pay too much attention and I said, "What's the package, Lee?"
And he said, "Curtain rods," and I said, "Oh, yes, you told me you was going to bring some today."
That is the reason, the main reason he was going over there that Thursday afternoon when he was to bring back some curtain rods, so I didn't think any more about it when he told me that.
Also worth noting is Frazier's constant assertion that he never payed much attention to the bag, which could mean that he really didn't give a stuff about Oswald's sack which means any size guess is worthless, or he perfectly knew in hindsight that Oswald had a rifle so Frazier tried his utmost to paint himself as innocent?
Mr. BALL - Did it look to you as if there was something heavy in the package?
Mr. FRAZIER - Well, I will be frank with you, I didn't pay much attention to the package because like I say before and after he told me that it was curtain rods and I didn't pay any attention to it, and he never had lied to me before so I never did have any reason to doubt his word.
Mr. BALL - Well, from the way he carried it, the way he walked, did it appear he was carrying something that had more than the weight of a paper?
Mr. FRAZIER - Well, I say, you know like I say, I didn't pay much attention to the package other than I knew he had it under his arm and I didn't pay too much attention the way he was walking because I was walking along there looking at the railroad cars and watching the men on the diesel switch them cars and I didn't pay too much attention on how he carried the package at all.
Mr. BALL - You will notice that this bag which is the colored bag, FBI Exhibit No. 10, is folded over. Was it folded over when you saw it the first time, folded over to the end?
Mr. FRAZIER - I will say I am not sure about that, whether it was folded over or not, because, like I say, I didn't pay that much attention to it.
Mr. BALL - But are you sure that his hand was at the end of the package or at the side of the package?
Mr. FRAZIER - Like I said, I remember I didn't look at the package very much, paying much attention, but when I did look at it he did have his hands on the package like that.
Mr. BALL - Mr. Frazier, we have here this Exhibit No. 364 which is a sack and in that we have put a dismantled gun. Don't pay any attention to that. Will you stand up here and put this under your arm and then take a hold of it at the side?
Now, is that anywhere near similar to the way that Oswald carried the package?
Mr. FRAZIER - Well, you know, like I said now, I said I didn't pay much attention--
