anyone working out of RV as you full time?

Unless you use a portion of the RV exclusively for business (unlikely), no deduction is allowed. By definition, a fulltimer can't be using any portion of the RV exclusively for business.

Jackson TC Memo 2014-160. 8-7-14

Interest on your home (RV) is deductible in most cases on Sch A.(As a personal, not business item.)

Full timed for 10 years, worked out of the rv for all of them. Could not take any deductions for home office, had H & R Block do the taxes for all 10 years in at least 4 different states. Unless you have a room dedicated to an office and it is used strictly for the business, you cannot take any deductions. The only RV deduction we were ever able to take was the 2nd home interest, of course, you can take deductions for your business. Just be sure you keep good records and receipts.

Home office are considered a red flag for the IRS, so you might get surprised with an audit.

Probably no different than living in a regular house.

I know I can talk to an accountant. I would like to talk to someone who has done it or is doing it. Thanks for the help. If a small business is run out of an RV (like a travel business/or RV education business) I read where many things associated are deductible.)

It is not a " major " deduction. It MAY count as a " home office ", which makes percentages of utilities, rent/ mortgage, etc, deductible.

It is done all the time with houses, so it is very possible.

I would suggest asking your account, and not relying on an internet forum for tax advice. Just sayin :-)

Lots of people do. Tax breaks? Nope. None that I know of except the deduction for finance interest as a second home.
