RV Trip Planner: How to Plan a Drive in a Motorhome

An RV changes the arithmetic of a road trip more than people expect. You drive slower, you stop more, you burn two to three times the fuel, and where you sleep stops being a detail you can settle at six in the evening — it becomes the thing the whole day is planned around.

This is how to plan around those constraints, including the one every planning tool is quiet about: none of them, ours included, routes around your rig's height and weight.

1. Plan shorter days than you think

A motorhome cruises slower, accelerates slower, and turns a 400 km car day into something closer to six hours behind the wheel. Add a fuel stop that takes longer because not every forecourt is usable, and the sensible daily ceiling drops sharply.

VehicleComfortable dayWhy
Car300–400 kmAbout 4–5 hours at realistic average speeds
Campervan250–300 kmSlower cruising, more frequent stops
Large motorhome200–250 kmSlower again, plus arrival-and-setup time at the site

The other reason to keep days short is arrival time. Pitching in daylight is not a preference, it is how you avoid reversing onto an unfamiliar pitch in the dark with someone directing you by phone torch. Aim to arrive by four.

2. Route around campgrounds, not attractions

In a car you choose a town and then find a hotel; there is nearly always something. In an RV the site comes first: the ones with the right hookups, an open season and a pitch long enough for your rig are a much thinner list, and in July they fill.

So build the route backwards. Find the sites that work, then decide what to see between them. Our planner does this when you pick RV as the vehicle — overnights become real campgrounds and RV parks rather than hotels, and the days are paced to reach them.

3. Budget fuel honestly

This is where RV budgets go wrong. A car at 6.5 L/100 km and a motorhome at 22 L/100 km are not the same trip with a bigger vehicle — over 2,000 km that is roughly 130 litres against 440. At €1.75 a litre, €228 against €770.

Use your real figure rather than the brochure's. Loaded, with bikes on the back and a headwind, most motorhomes do worse than their quoted consumption, and mountain routes worse again.

4. The practical rhythm of an RV day

  1. Service before you leave, not when you arrive: water, waste, and a quick check of the tyres.
  2. Drive the long leg first, while everyone is fresh and the light is good.
  3. Stop somewhere with space to park — an out-of-town supermarket beats a medieval centre every time.
  4. Arrive by four, pitch, then explore on foot or by bike. Unhitching to sightsee is why so many RV travellers end up seeing only campsites.

Fold a bike or two into the plan if you can. The single biggest quality-of-life change in a motorhome trip is not having to move the vehicle to see a town.

5. What no planner checks: your rig's dimensions

This section is here because it is the most important thing on the page. Our planner — and, as far as we can tell, every consumer planner in this price range — routes for a car. It does not know your vehicle's height, length or weight, and it does not avoid low bridges, tunnels with height limits, weight-restricted roads, or the tight switchbacks that a long rig physically cannot take.

Check clearances and restrictions yourself before you drive an unfamiliar route. A generated itinerary is a plan for where to go, not a certification that a 3.2 m vehicle fits under everything on the way.

We would rather say this plainly on the page that ranks for RV planning than let someone discover it at a bridge. If size-aware routing ever becomes affordable to license, we'll add it and say so here.

6. If it's your first motorhome trip

Rented rigs come with a twenty-minute handover that covers roughly a third of what you need. The things people learn the expensive way are all small.

Budget too. A campsite pitch with hookups runs roughly €25–50 a night in Europe and $40–90 in North American private parks, before fuel — which means an RV trip is not automatically cheaper than hotels, and is usually only cheaper if you use basic sites or aires for part of it.

7. Routes that suit a motorhome

The best RV routes have short hops, generous parking and a campsite network that stays open. Coastal roads and national-park corridors qualify; dense historic regions rarely do.

Questions, answered

How many miles a day should you drive in an RV?
Around 150 miles (250 km) for a large motorhome and up to 200 (300 km) for a campervan. The limit is arrival time as much as distance: pitching in daylight matters, so aim to be at the site by four in the afternoon.
Does an RV trip planner account for my vehicle's height?
Ours does not, and most consumer planners do not — they route for a car. Height, length and weight restrictions have to be checked separately, ideally with a truck or RV-specific navigation app for the driving itself.
Should I book campgrounds in advance?
For summer, coastal sites and anything near a national park, yes — those fill weeks out. Midweek and inland you can usually arrive on the day, but always have a fallback in mind rather than relying on it.
How much fuel does an RV use?
A large motorhome runs around 20–25 L/100 km (roughly 10–12 MPG); a campervan is closer to 9–12 L/100 km. Use your own measured figure if you have one — loaded and in the mountains, most rigs do worse than the quoted number.
Can I plan an RV trip and a car trip the same way?
No. The two differences that matter are shorter driving days and campground-first routing: in a car you choose a town then find a bed, in an RV the site availability decides the route.
