We do! Ours is a 45ft long deisel pusher. It weighs 45,000 lbs. Before that we had a class B, before that a 22ft pull behind class C(my nostalgic favorite).
There's my qualifications! Ha!
My husband travels frequently & stays in hotels about 160 nights per year.
He can not use our RV for work......or he would.(which is why I'm reccomending that your husband should-since we know A LOT about hotel travel)
We home educate, so RV when possible(we are vacationing in Creede Co right now, Big Bend this past February, Hill Country of Texas in Fall, 6 week trek of southern US, 6 week trek of East coast & Smokey Mountains, etc).
We belong to Good Sams, it pays for towing, emergencies, etc. Well worth the small annual fee.
Also we belong to internet RV clubs for our particular brand of RV---gives us instant friends who could help us in a pinch--either on-line, the phone or in person. I'd highly reccomend joining a group.
We overnight in (free/no cost)friends driveways, truck stops, rest areas, Walmarts, etc... only once in a 'Blue Moon'. Also ALL texas rest stops now offer free wi-fi.
Most places cost $10-18 per night with cable/internet hook-ups. We have paid up to $36 for RESORT RV accomodations.
Good Sams publishes a book of ALL RV places nationwide, lists ratings of facilities, options, prices(it's cheaper to buy the book (called Trailer Life)if your're a Good Sams member---)$14-24
Your hubby could set up an office on the kitchen table that stays conveniently set up. Use his OWN shower/toilet/bed. Eat his own food(sandwiches, fruit, healthy snacks & homemade meals when he's not too tired,) and NOT high calorie/fried hotel/motel food. Big plus plus!(our RV bed is fabulous & I love sleeping in it) You can help him pack it & give him some loving family touches/treats...... He won't HAVE to chat with co-workers while checking in/out. IF an appt. takes too long-- he won't care, check out time is typically later than motels. RV parks include state/national parks. The birds/trees are so relaxing.
RV's are super cheap right now. HINT-Buy privately from elderly folks that were ex-military..... will be well maintained & spotless! They are easy to find, due to gas prices. Get one w/ stackable washer/dryer... awesome(but RV parks also offer showers, laundry facilities, etc)
Renting is a wonderful idea so that he can get used to 'bulky' driving, set-up/tear-down checklists, etc.
Will he be towing a car? If not, then I'd get a Class C that the car/truck tows the RV, so he has a vehicle to go around in to all types of insurence claime areas.
Hope that helps. T. <>-<<
PS--- he can use it as a tax write-off, plus more, call you accountant
