Jay Flight 287BHSW- is Underbelly important?

Looking to buy this Jay Flight 287BHSW this weekend. It's our first RV... we are pretty limited in our options as we are pulling with a SUV (so we have a weight limit) and need double bunks and a shower only (no tub) as my husband is 6'4 and can't stand in the shower tubs. This is a difficult combination to find but we did find it in the Jay Flight 287BHSW. This is the "Stripped Down" version of JAYCO as the sales guy calls it. We are actually ok with that as we don't think we care about having the TV, DVD players, automatic leveler and some of the other bells and whistles that won't be included in this model. The one thing we are a bit nervous about is that it doesn't have the Underbelly. Does anyone have thoughts or advice on a RV that doesn't have this? We want to make sure we aren't selling ourselves short just to save a few dollars up front. Thanks for your help!

Welcome to the forum.

The insulation package provides insulation in the belly and in the roof. It helps to extend the camping season into the cooler months and reduces the load on the air conditioner(s) in the summer.

Beyond that, some like the fact it may help reduce the chances of bugs or mice getting into the unit, it may reduce some noise infiltration, keeps road crud from building up under the trailer, and some believe it reduces air resistance for better mpg.

We ordered the package strictly to reduce the load on the air conditioner during the warmer months. If it does anything else, that would be a bonus. I'm sure you'll be hearing soon from others and their take on the insulation package.

The covered underbelly also helps keep road crud, salt, oil, etc from getting onto all your tanks, tank sensors, plumbing, etc. under there.

I specifically did not order mine with the thermal package. I liked the idea of having the extra insulation, but I did not care for the way the underbelly looked or how it was attached. It also limits the access to all of the components underneath for inspection and maintenance. If you like the layout, go for it.

Got the same trailer, it's bothered me how the slide mechanism was exposed, bought corrugated ABS , double sided foil insulation and closed the entire underbelly, it is much warmer floor as a result, you can have a dealer to close it for you as well, if you decide to go that route , have them to install holding tank heating pads on all tanks before you close it , comes handy when camping in freezing temperatures

I have not had the thermal package on either of my JayFlights. The first one I was a bit like you, had some concerns I was making a mistake, but then figured I could enclose it myself should I need too. Well I didn't, and it was a non issue for me on my second unit.

We just camped over New Years, night time lows at 25*-28*, coldest we have ever taken this trailer, absolutely no issues with tanks freezing.

Ours is not enclosed and it has been a non-issue so far.

I think before you jump into a camper that size, the question needs to be asked...What SUV tow vehicle do you have? That camper is rated to 7500 GVW and that is the limit of many 1/2 ton trucks mostly due to the wind resistance.

On the underbelly...I like it being open. We had a loose fresh water tank fitting that leaked onto the ground that I fixed. If we had the underbelly, it would have filled with water before we found the leak.

Ours is enclosed and it might keep mice at bay to some extent and hold the heat better but it is and has been a pain when you have mechanicals to deal with ... you can get to them but it takes some work. .. in the end i still like it being enclosed
