The worker at Homedepot said I could not run my RV off of an extension cord like that because I will lose voltage drop at 40'
When the worker at Home Depot hears "Extension cord" he thinks about the 16Ga jobs they sell in the extension cord isle.. He does not know nor has he ever (in all likelyhood) seen an extension cord rated for 30 amp RV use such as you'd find at Camping World or ____'s RV sales and service.
We are talking about that kind of cord, I has TT-30 Plug and socket not the standard wall type socket and plug, And it is SPECIFICALLY designed to supply an RV over that distance. In fact, it is heavier than what the HomeDepot guy suggested. So it is the better deal.
One suggestion: Unless you are doing it yourself and KNOW what you are doing (As I did) When the House builder's electrican puts in that 30 amp outlet for you do two things.
1: Confirm it has SINGLE 120 volt breaker, (Ok the breaker can be rated higher but make sure it is a single not a dual ganged or a wide single that takes up two slots).
2: METER the outlet to insure it is 120 and not 240 volt before you plug in.
Once that's done LABEL IT (Brother P-touch or commercial "Badge maker" engraved plastic): 120 volt 30 amp RV
