If your lot is zoned residential, I don't think you can legally do it. Take a look at the Pasco County regulation in the link,
Pasco County, FL - Official Website - RV Parking
Here's a more complete writeup of the actual statute - I highlighted a few items in red that would seem to prohibit you from doing what you want.
Parking or Storing of Recreational Vehicles
A. Recreational vehicles (RVs) may be parked or stored anywhere
on residentially zoned property that is one (1)acre or more in
size, provided they are not parked or stored within a twenty-five
(25)foot setback from the front property line, and provided they
are parked or stored at least five (5)feet from a side or rear
property line. Vehicles parked in an E-REstate-Residential
Zoning District are subject to the regulations in SubsectionB.,
below, regardless of the size of the property.
B. On residentially zoned property less than one (1)acre in size, or
on E-REstate-Residential zoned property of any size, RVs are
subject to the following regulations:
1. RVs may be parked or stored in the side yard or rear
yard provided that:
a. No more than one (1)side yard on any property is
used for such purpose.
b. No part of the RV may be parked or stored in front
of the principal building line of the primary
residential structure or between any structure,
accessory structure, or part of such structure, and
the front yard. This section is intended to restrict
such parking in front yards and front driveways as
commonly construed.
c. RVs may not be parked in any location less than
five(5)feetfromanyrearorsidepropertyline.
d. RVs shall be screened from view from all abutting
property by an opaque six (6)foot fence or by
vegetation which is at least seventy-five
(75)percentopaqueandatleastsix(6)feethigh .
e. For double frontage or “corner” residential
properties, no RVs shall be parked or stored on
the side of a home bordered by a roadway.
f. For residential properties that have a garage or
carport that protrudes past the principal building
line of the residence where the front door is
located (an “L-shaped” or “U-shaped” structure),
the “principal building line of the primary
residential structure” is that building line parallel to
the front door and not to the front protruding edge
of the garage or carport. Under no circumstances
shall RVs be parked or stored in a location where
the distance from the front door to the front
property line is greater than the distance from the
front protruding portion of the RV to the front
property line. Any person may seek a written
determination from the County Administrator or
designee identifying the “front door” and/or
“principal building line of the primary residential
structure” for residential property owned or leased
by that person.
C. The following provisions apply to all RVs parked or stored on
residentially zoned parcels:
1. RVs may not be parked or stored on any residentially
zoned property where there is no primary residential
structure. .
2. RVs may be temporarily parked in the driveway on a
residentially zoned lot for loading, unloading, and cleanup
during the times a person is in fact physically engaged in
the act of loading, unloading, or cleaning the vehicle.
Campers and motor homes of all types may be
temporarily parked in the driveway for trip preparation,
loading, unloading, and cleanup for up to seventy-two
(72) hours in any seven (7)day period, up to four (4
)times per calendar year.
3. RVs may not be repaired on residentially zoned property
unless parked in accordance with this section and unless
owned by the owner-occupant or occupant-lessee of the
property. No more than one (1)RV on the property may
be in need of repair or under repair. This is intended to
limit large-scale or continuous repair or restoration of
RVs on residentially zoned property, whether for
commercial or noncommercial purposes.
4.
RVs shall not be connected to water, sewer, or electric
lines, except that properly parked or stored RVs may be
connected to battery chargers. It shall be unlawful, at
any time, to use RVs parked or stored on residentially
zoned property for residential purposes, except that
(1)park trailers may be occupied temporarily for
residential purposes within properly zoned campgrounds,
RV parks, and RV subdivisions; and (2) houseguests
may temporarily occupy an RV in accordance with
Section530.1.C.8 below. Otherwise, the use of RVs for
activities, such as sleeping, housekeeping, living
quarters, bathing, dressing, watching television, working,
reading, writing, working on hobbies, or other similar
activities is considered use of the RV for “residential
purposes,” and is prohibited, even if such activities are
confined to the daytime hours and the RV is not occupied
overnight. Utility, water, electric, sewage, generator, or
cable connections to an RV create a presumption that the
RV is being used for residential purposes. This
presumption may be rebutted only with clear and
convincing evidence.
5. No RV parked or stored on a residentially zoned property
shall be used for commercial purposes.
6. No RV shall be parked or stored on the right-of-way. No
portion of an RV shall extend over, or interfere with, the
use of any sidewalk or right-of-way intended for
pedestrian or vehicular traffic.
7. An unlimited number of RVs may be parked or stored
within a completely enclosed, permanent structure on
any lot in a residentially zoned district, provided the
enclosed permanent structure meets all applicable
construction codes and a valid Building Permit exists for
the structure.
8. Parking or storage of RVs on any residentially zoned lot
shall be limited to RVs owned or leased by the occupantowner
or occupant-lessee of the lot.
a.
A vehicle owned or leased by a person who is not
a resident of Pasco County and who is a
houseguest of the occupant-owner or occupantlessee
of the lot may be parked or stored on the
lot for a period not to exceed ten (10) days, four
(4) times per calendar year, provided that it is
parked in accordance with the other regulations in
this section.
(1) Guest RV parking shall be in accordance
with all other provisions of this section,
including set backs, except that it may be
temporarily used for residential purposes.
(2) A Guest RV Parking Permit must be
obtained prior to parking the vehicle on the
property and must be prominently
displayed.
(3) At least thirty (30)days must lapse before
guest parking will be permitted on the same
property.
b. RVs may be parked in areas zoned for multi
ple-family residential use, provided that such
areas are approved for such use by the owner of
the property and included in the approved site plan
for such property.
9. Applicability. This section does not apply to trailers that
are used or designed for commercial purposes, which
bear commercial markings or advertisements, or which
contain “commercial equipment” as defined by this Code.
Such trailers must be parked or stored in accordance
with the regulations in Section 530.19 concerning the
parking or storage of commercial vehicles o
