to the Jayco Owners Forum! Sorry to hear about your loss in your divorce. Been there; done that; got the T-shirt. But congratulations on your new adventure!
I've been full-timing for 7-1/2 years, now, and may be able to offer some insight. Before you make your decision, ask yourself "Where will I be staying, how long will I be staying in each location, and what will be the distance between stops?"
Will you be staying in private or public campgrounds (state parks)?
1) If you'll be staying in private parks with full hook-ups, either one should suit your needs quite well. But, you may want to reconsider your need for a washer/dryer. Most private campgrounds have a laundry room for guests to use. And, since you'll need 4 seasons worth of clothes (for both work and leisure), you'll need the clothes-storage space you can get! If they don't have a laundry room, there's generally a public laundry in a nearby town. That's what I use. I can do a month's worth of laundry in about three hours (including travel time).
If you'll be staying in public campgrounds, then you may want to purchase a trailer with the largest fresh/grey/black storage tanks you can find - so you don't have to drag a sewage tote around, or pull up stakes & take your rig to the dump station every 3-4 days. And the washer/dryer will only deplete your FW tank, and fill your GW tank(s) faster.
2) If you'll be staying at each location for more than a couple of days, you'll want as much countertop space as you can get. You won't want to be digging out your coffee maker, toaster, and can opener every day; then putting them back into storage, so you have enough countertop space to make dinner and do your dishes. And while I'm on that subject, heavy-duty paper plates can save a ton of water, since you don't have to wash them.
3) What will be the travel distance between stays, and what will the weather be like when I have to move? If you'll be moving every day or two, and don't need your truck for work, you may want to consider a motorhome rather than a travel trailer - especially considering you'd be pulling a 35'/10.000 lbs. box behind you in high winds and heavy snow on winding mountain roads. I'm sure you can pick up a nice, small toad for what you'd get in trade for your nearly-new pick-up. As you can see, I pull a 30' TT, (sometimes in Michigan snow storms) so I have some experience doing that.
Just give your plans a little more thought, and I'm sure you'll make the right decision for YOU
. Best of luck with your decision and your travels, and be sure to let us know about what you choose.
