Most full-timer workcampers I've met have 5th wheels - say 60%.
The opening slides of a 5er floor plan appeal to many folks who will be staying put for several weeks/ months at a time. And are willing to trade that for the poor fuel mileage and limited maneuverability of a big dually pickup for those months. Almost all the 5er camp hosts/ workampers I know have 1 ton trucks - many started with F-250/2500 3/4 ton trucks and had to upgrade to a more expensive truck.
Today - 5ers no longer had an advantage in floor plans - you can get almost any 5er floor plan in a TT.
We have a TT with opposing slides and a 5th wheel type floor plan. We don't have the under bedroom storage area of a 5er. That's the big disadvantage.
But I know several camp hosts/ workampers who use TT - say 20%. I've seen everything from a 17' long Casita to a 40' Eagle TT used by camp hosts.
Class A or Class C units - make up 15% in my estimation. Some of these are full-time some are not. I've worked with a couple in a 20+ year old Toyota Class C and a couple in a brand new 43 ft Entegra Anthem. Most common are gas class A units for working campers of the self-propelled units.
We also worked with a mother and adult disabled son who work camp out of a Roadmaster B+. They've worked from Denali NP to south Texas - and many places between.
There are also some workampers who use pickup campers - and even one fellow with a volunteer maintenance position at the COE park where we are located right now in a tent.
The US Forest Service has a lot of volunteer positions which are dry camping with no hookups available, and often you have to go and truck in your own water.
Most camp host/ workamper positions will have a full-hooks-ups site - 50A / W/ E - but there are some which have limited electricity, or no sewer.
My wife vetoed applying to Assateague Island National Seashore because there was no sewer connection. Have to use the SewerTote to empty the tanks. She wasn't going to go for that for four or six months.
Remember - you are going to trade your home for 250-300-325 square feet of living space. That's small.
You are going to have to have everything you need to live, to work on the rig, to enjoy life, in the rig with you.
Do be aware that no matter what you get - you are going to be very close to the maximum weight capacity of the rig. That's just the nature of the beast. You don't want to decide you need the winter sweaters - sitting in a box in storage 1,000 miles away, or the swimsuits either.
Sometimes I think the ideal rig would be a toy-hauler with an 8-foot garage as a storage room/ walk-in closet.
Some 'musts' in my opinion.
1) Wife is happy with the kitchen area. Yes, many of us like cooking outside on the grill. But as a volunteer/workamper you are going to have to cook a great many meals inside. Useful storage is essential.
2) A bathroom/ shower you can get clean in. Some of the newer 5er and TTs floor plans have 48x30 or 60x30 showers with a seat. Those are great.
3) A true three seasons rig. You can't decide to pull out and go to the mountains if the temps spike to 100+ degrees, nor if the temps drop to the teens overnight. That includes provisions to keep the fresh water hose from freezing.
4) Comfort in driving the rig. Enough truck to tow a heavily loaded 5er/TT, or a Class A/C/B that drives comfortable. One of the greatest things about full-timing and volunteering/ workamping is that you can literally go from one coast one summer to the other coast the next.
5) Comfortable means to drive around and explore. You will have the luxury of not having to rush around every day for hours to see 'everything'.
But the very most important thing - get a rig and tow vehicle or toad - that fits your budget. Don't spend more than you can afford. Don't go into debt if at all possible.
That also means getting a rig your continuing income can support. A 20 year old DP might have a great price - but if you cannot afford what the diesel shop charges for yearly maintenance - it's too expensive.
