Do not have to be old to own a Motorhome

No you dont have to be old, but it helps. Unless independently wealthy or something the younger folks will not utilize as much as older. The rig will stay parked more than used. Older will not vary much but will tend to be used a little more IMO. I am not referring to full timers here. We had a slide in pu camper used the******out of it for several years with the 2 younger kids. They went to HS and we used it less. Work demands required I go to La. for several weeks and there were no lodging capabilities in the area. We bought our TT usd it for the entire summer for the work lodging as well as a vacation unit. Got home only used a couple of times after that. about 5 years later decided to do more traveling got new truck and off we went. Did this for several years during summers. Unit sat idle most of time. Now wife wanted RV, still have truck and trailer. Bought the rv, used in a couple of times for dry runs, once this past summer for 6 weeks, now will be next year until its out on road. We both still work plus with winter coming we live in a place where there is no need to move in an rv soooo.

Anyhow, the basic premiss is correct, but just how old do you need to be to really use it effectively. A slide in if they were affordable with a right size truck is actually the best IMO for people with young kids. Park the slide in still have the truck, without extra insurance payments etc. Depending where they live the slide in can be parked in the yard/driveway, an RV may have to go to a storage lot. So it is all very dependent on how you look at want to do rving.
